Workplace Investigations

There is no specific legislation regarding a workplace investigation. In general, an employer has the right to investigate incidents at the workplace based on their authority over employees. However, the investigative powers of the employer are among others limited by the general right to privacy, which is also enshrined in Collective Bargaining Agreement No. 81 of 26 April 2002 to protect the privacy of employees concerning the control of electronic online data. If there are official complaints by employees due to sexual harassment, bullying or violence at work,  well-being legislation provides a specific procedure. Also, upcoming whistleblower rules include some specifications for an investigation, but at the time of publication these are not yet final (we refer to is in more detail below). The information below is only valid for workplace investigations in the private sector. The public sector has a set of specific rules and principles, which are outside the scope of this chapter.

Mainly, the Occupational Safety and Health Act (738/2002). In addition, the following also have relevance in connection to a workplace investigation: the Employment Contracts Act (55/2001), the Criminal Code (39/1889), the Act on Occupational Safety and Health Enforcement and Cooperation on Occupational Safety and Health at Workplaces (44/2006), the Act on Equality between Women and Men (609/1986) and the Non-discrimination Act (1325/2014). In addition, the employer's own policies must be taken into consideration while conducting a workplace investigation.

In the UK, the primary employment legislation of relevance to a workplace investigation includes the Employment Rights Act 1996 (ERA 1996), the Equality Act 2010 (EA 2010), and the Employment Relations Act 1999 (ERA 1999).

Other legislation includes the retained EU law version of the General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018), the Investigatory Powers Act 2016 (IPA 2016) and the Investigatory Powers (Interception by Businesses etc for Monitoring and Record-keeping Purposes) Regulations 2018 (IP Regs 2018), and the Humans Rights Act 1998 (HRA 1998).

In terms of guidance, the Advisory, Conciliation and Arbitration Service (ACAS) have produced a Code of Practice on Disciplinary and Grievance Procedures (the ACAS Code) as well as a Guide to conducting workplace investigations. The Information Commissioner’s Office (ICO) have their Employment Practices Code,  and other pieces of guidance on the data protection aspects of investigations (see question 7).

Most employers will have internal policies governing how workplace investigations should be conducted. The level of detail may vary considerably; public sector and regulated employers may be more prescriptive in their policies, which may even have contractual force. There may also be provisions of the employment contract that are relevant (particularly as regards suspension – see question 3).

First, the employer should appoint an investigator or investigative team that will be responsible for conducting the investigation. Next, the employer or the investigators might think about communicating with the involved employees. It depends on the situation if this is a good idea or not. In general, it can be recommended that the employer is transparent towards the involved employees and openly communicates about the (start of the) investigation process. This is definitively the case if it is already clear that the involved employees are under scrutiny because of their actions. In this case, the actual investigation can begin with a hearing of the involved employees. However, if there is a risk that employees will hide or destroy evidence or will collude to prevent the employer from finding the truth, the investigation can also start without any communication. In this case, it would be better to start collecting evidence before hearing from the employees involved.

When the employer becomes aware of possible misconduct, the employer must commence an investigation immediately, in practice within about two weeks. The information may come to the employer's knowledge via, for example, the employer's own observations, from the complainant or their colleagues or an employee representative.

The trigger could come from several sources, such as a grievance from a current or former employee, a complaint from external sources, a whistleblowing disclosure, or as the result of internal governance measures.

In each case, the employer will need to decide if an investigation is warranted. It may be required by internal policies or regulatory requirements in some circumstances. Consideration must be given to whether an investigation is feasible; for example, is the evidence still in existence and accessible? Are key witnesses still employed or contactable?

If the employer concludes that an investigation is warranted, it should start without unreasonable delay. The first step would usually be to set terms of reference, which outline the purpose and remit of the investigation. These should be closely drafted and continually referred to, to avoid the investigation’s scope expanding when new points arise (as they almost always will). An investigator will also need to be appointed (see question 4).

In principle, you cannot unilaterally suspend an employee during a workplace investigation, as there is a risk of constructive dismissal (ie, wrongful termination of the employment contract by the unilateral modification of one of its essential elements). Consequences could include the payment of an indemnity in lieu of notice based on seniority as foreseen by the Employment Contracts Act, plus possible damages (three to 17 weeks remuneration if an unreasonable dismissal, plus alternative or additional damages based on real prejudice suffered). The parties can nevertheless agree on a suspension of the employment contract. In this scenario, the remuneration will still have to be paid. Furthermore, a suspension could be a sanction that follows the outcome of the investigation, but even then it will only be possible for a limited time (and a suspension without pay is usually only allowed by the courts for a maximum of three days). However, if the complaint is about sexual harassment, bullying or violence at work, the prevention advisor (see question 4) can recommend that the employer take certain actions, which in grave circumstances could lead to employee suspension. The suspended employee should continue to receive his pay if this occurs.

There is no legislation on temporary suspension in the event of a workplace investigation or similar. In some situations, the employer may relieve the employee from their working obligation with pay for a short period.

In the UK, suspension is not seen as a neutral act, so should not be a default approach at the start of an investigation. It may be appropriate if, for example, there is a risk to the health and safety of the employee in question (or any other employee), a risk that their continued presence in the business could prejudice the investigation, or risk of continued wrongdoing.

The employer should always check the individual’s employment contract to see if it contains the power to suspend. Suspension should generally always be with pay to avoid any breach of contract. It should also be regularly reviewed and kept to a minimum duration.

Employers should not suspend employees under investigation as a knee-jerk reaction to bare allegations. There must be at least some evidence to support the need for suspension (which may require a preliminary investigation before deciding to suspend). Alternatives to suspension should always be considered, such as a temporary transfer to a different area of work, if the employee agrees or it is otherwise permitted by their contract.

If authorities such as regulators or prosecutorial agencies are involved in the investigation, they may have an opinion about an employee’s suspension, particularly if they wish to conduct interviews. Consider whether or not to involve the authorities in the suspension discussions at an early stage.

ACAS have produced a guide to suspension during investigations (last updated Sept 2022) which gives further guidance on these issues.

In general, there are no legal minimum qualifications, the employer can delegate the investigation task to anyone. Of course, it is strongly recommended to appoint someone who is not involved in the case and who can lead the investigation objectively with the necessary authority to take investigative measures.

However, in the specific case of an official complaint due to sexual harassment, violence or bullying at work, the investigation will be conducted by the prevention advisor for psychosocial aspects. Next, if the investigation is based on an internal whistleblowing report, there will have to be an independent reporting manager responsible for receiving the report, giving feedback to the whistleblower and ensuring a decent follow-up to the report. Logically, the reporting manager will lead the investigation in this case, but he can be assisted by other persons or a team who are bound by a duty of confidentiality.

The employer must conduct the investigation, but the actual work can be done either by the employer's personnel or by an external investigator, for example, a law firm. Either way, there are no formal criteria for the persons executing the investigation; however, impartiality is required from the person conducting the investigation

The investigator would typically be a line manager or HR representative. Complex cases, particularly if criminality is suspected, or cases where a senior employee is accused of misconduct, may require the investigator to be someone more senior within the organisation, or someone from the in-house legal team. Employers should bear in mind the need for someone more senior than the investigator to act as a disciplinary decisionmaker, if disciplinary action is found to be warranted.

Check the organisation’s policies and procedures, which may stipulate who can act as an investigator.

The investigator should be someone without any personal involvement in the matters under investigation, or any conflict of interest, but with sufficient knowledge of the organisation and where possible with both training and experience in conducting investigations.

The business should consider how any prospective investigator may appear if they are called as a witness in court, or to give evidence before any governmental committee or regulatory panel. They should also consider whether the employee accused of wrongdoing should have any say in the choice of investigator; this would not typically occur, but having the employee’s buy-in can increase the chances of a successful outcome to the investigation.

It is becoming increasingly common for businesses to use an external consultant or lawyer to conduct workplace investigations. This may be beneficial where it is not operationally viable within the employer organisation to have a different person conducting the investigation and the disciplinary hearing, or if the investigation is particularly sensitive or complex, or relates to a very senior employee. If an external investigator is appointed, the employer remains responsible for that investigation.

This is only possible if the employee claims that his or her rights (eg, the right to privacy) are violated by the investigation (but this will merely limit the investigation methods) or if he or she finds that the investigation constitutes an abuse of rights. In any case, it will be very hard for an employee to completely halt the investigation.

The employee does not have a legal right to stop the investigation. The employer must fulfil its obligation to investigate the alleged misconduct.

Not usually, unless the investigation is being conducted in breach of a contractual policy (as sometimes happens in the NHS, for example), or if the investigation is not adjourned pending the outcome of criminal proceedings, and the employee can show that failure to do so is a breach of either an express term or the implied term of trust and confidence. The latter would be rare, but possible if the employee can demonstrate a real danger of a miscarriage of justice (see question 21).

Employees cannot be forced by their employer to act as a witness. If they decide to nonetheless testify as a witness, they do not, in principle, have particular rights. If the employee puts himself in a difficult or even dangerous position to act as a witness, it is up to the employer to offer the necessary protection or take measures to prevent any harm (eg, by keeping the identity of the witness confidential or by planning the hearing at a place or time when the employees involved are not aware of it).  

However, this is not the case for whistleblowing reports, where a witness might be seen as a “facilitator” who can receive protection against any retaliation by the employer.

Also, workers who were direct witnesses to official allegations of sexual harassment, violence or bullying at work are protected against retaliation by the employer. This also applies to witnesses in court.

There is no legislation on a witness's role in investigations. However, the legislation on occupational safety requires that employees must report any irregularities they observe. Depending on the situation, participating in the investigation may also be part of the person's work duties, role or position, in which case the employer may require the employee to contribute to clarifying the situation. However, there is no formal obligation to act as a witness, and there is no legislation regarding the protection of witnesses. If a witness wishes, they may have, for example, an employee representative as a support person during the hearing. 

Employees may be reluctant to be interviewed or act as witnesses as part of an investigation, perhaps due to fear of reprisals. The investigator should discuss any concerns with the employee and attempt to alleviate any fears.

In general terms, an employer should not compel any employee to provide a witness statement. There may be circumstances in which this could be seen as a reasonable management instruction (and any refusal to comply treated as a disciplinary matter), but these will be rare. Evidence that is compelled is unlikely to be particularly useful to the investigator.

It may be possible to establish an express or implied obligation for senior managers to report on another employee's misconduct – as a feature of either their employment contractual duties, their fiduciary duties or their implied duty of fidelity. However, it is unlikely, in the absence of an express obligation, that a junior employee would be compelled to give evidence against a colleague.

Employees who act as witnesses benefit from their usual employment protections, and must be treated as per their contractual and statutory rights, as well as any policy governing the investigation. If the investigation involves allegations which could involve discrimination, the EA 2010 extends protection from victimisation to “giving evidence or information in connection with proceedings under this Act”. Witnesses should therefore not be subject to any detrimental treatment because they have acted as a witness in this type of investigation. Witnesses may also be entitled to protection as whistleblowers if their evidence amounts to a protected disclosure (see question 9).

Here, the investigation “collides” with the right to privacy of the persons involved.

First, the rules and principles of the GDPR will apply if personal data is involved. Therefore, the employer will have to find a data-processing ground, which could be his or her legitimate interest or the fact that the investigation could lead to legal proceedings, etc. The data processing should also be limited to what is proportionate and the data subjects should be informed. Due to this obligation, it is arguable that the GDPR policy already provides the necessary information for the employees not to jeopardise the investigation. In any case, data subjects should not be able to use their right to access data to ascertain the preliminary findings of the investigation (which are confidential) or any confidential identities involved (eg, in the whistleblower procedure, the identity of the report should be protected at all times).

Also, the employer should follow the procedure of Collective Bargaining Agreement No. 81 on searching the e-mails or computer files and internet searches of employees. This CBA limits the purposes for searches and lays down a double-phase procedure that needs to be followed if private data is involved. Next to this, the employer should also take into account the case law of the European Court of Human Rights, which only allows e-mail and computer searches based on the following:

• whether the employee has been notified of the possibility that the employer might take measures to monitor correspondence and the implementation of such measures;
• the extent of the monitoring and the degree of intrusion into the employee’s privacy (including a distinction between the monitoring of the flow or the content of the communications);
• whether the employer has provided legitimate reasons to justify monitoring of the communications and accessing of their actual content; and
• whether it would have been possible to establish a monitoring system based on less intrusive measures, the consequences of the monitoring for the employee who is subject to it, and whether the employee had been provided with adequate safeguards.

Next, if the employer wants to use camera images, the rules of Collective Bargaining Agreement No. 68 should have been followed when installing cameras. If not, the images might have been collected illegally.

Generally, the basic principles set out by the GDPR and the Finnish Data Protection Act apply to data processing in connection with investigations, including evidence gathering: there must be a legal basis for processing, personal data may only be processed and stored when and for as long as necessary considering the purposes of processing, etc.

Additionally, if physical evidence concerns the electronic communications (such as emails and online chats) of an employee, gathering evidence is subject to certain restrictions based on Finnish ePrivacy and employee privacy laws. As a general rule, an employee’s electronic communications accounts, including those provided by the employer for work purposes, may not be accessed and electronic communications may not be searched or reviewed by the employer. In practice, the employer may access such electronic correspondence only in limited situations stipulated in the Act on Protection of Privacy in Working Life (759/2004), or by obtaining case-specific consent from the employee, which is typically not possible in internal investigations, particularly concerning the employee suspected of wrongdoing.

However, monitoring data flow strictly between the employee and the employer's information systems (eg, the employee saving data to USB sticks, using printers) is allowed under Finnish legislation, provided that employee emails, chats, etc, are not accessed and monitored. If documentation is unrelated to electronic communications, it also may be reviewed by the employer. Laptops, paper archives and other similar company documentation considered "physical evidence" may be investigated while gathering evidence on the condition that any private documentation, communications, pictures or other content of an employee are not accessed.

Most forms of workplace surveillance involve the processing of personal data that is regulated by the UK GDPR and DPA 2018. The UK GDPR requires that personal data must be processed lawfully, fairly and in a transparent manner; it also must be adequate, relevant and limited to what is necessary concerning the purposes for which it is processed.

Employers should ensure that they have undertaken a data protection impact assessment (DPIA) to document the lawful basis for processing data, and informed employees that their files may be searched before proceeding. They should also ideally have a clear policy on the use of electronic communications systems, detailing when, how and for what purpose they may be monitored by the employer. In Q3 2023 the ICO produced new guidance on monitoring workers (https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/monitoring-workers/) and on email and security (https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/security/email-and-security/) which employers should bear in mind during investigations. Employers should also be prepared to make the data collected through employee monitoring available to employees, should the employee submit a data subject access request under the DPA 2018.

The IPA 2016 makes it unlawful in certain circumstances to intercept a communication (such as one on an employer’s telephone or computer network) in the course of its transmission in the UK. The IPA Regs 2018 set out the circumstances where, in a business context, such interception will be lawful. These include monitoring or recording communications without consent to: establish the existence of facts; ascertain compliance with the regulatory or self-regulatory practices or procedures relevant to the business; ascertain or demonstrate standards which are or ought to be achieved by persons using the system; and prevent or detect crime.

Covert surveillance can lead to a breach of an employee's right to privacy under the HRA 1998. The employer will need to consider if covert surveillance is proportionate, which will depend on the facts of each case. Employers should be careful not to use the investigation as an excuse to undertake a "fishing expedition", and should avoid gathering material that is obviously personal, such as private messages and diary entries (see question 8).

The employer is, in principle, not entitled to search the employee’s private possessions, except with the explicit consent of the employee. Digital files on the computer or laptop of an employee can be searched under the rules of CBA No. 81 (see question 7) and other privacy rules.  

Only the police can search employees' possessions (assuming that the prerequisites outlined in the legislation are met).

It may sometimes be difficult to draw a clear distinction between the property of the employer and employees’ personal property, both physical and electronic, particularly where employees are increasingly working from home. Employers should ideally have a clear policy to delineate what is the employer’s property.

Employees typically have a reasonable expectation of privacy at work, although how far this extends will depend on the circumstances of each case and the employer’s policies.

When it comes to employees’ personal possessions, a search should only be conducted in exceptional circumstances where there is a clear, legitimate justification. The employer should always consider whether it is possible to establish the relevant facts through the collection of other evidence. Even if the employee’s contract specifies that it is permitted, employers would usually require explicit employee consent for the search to be lawful. The employee should be invited to be present during the search; if this is not feasible, another independent third party (such as a manager) should be present.  

If the employee refuses to consent to a search of their personal possessions, their refusal should not be used to assume guilt; the investigator should explore why the employee has refused and seek to resolve their concerns if possible.

If the employer believes that a criminal offence has been committed it should consider involving the police, since they have wider powers to search individuals and their possessions. 

If the investigation is based on a whistleblower report that falls under the scope of the upcoming rules, the investigators are bound by a strict duty of confidentiality, especially regarding the identity of the report. The rules also provide some procedural deadlines for feeding back to the reporter. Within seven days of receiving the report through an internal reporting channel, the reporting manager needs to send a receipt to the whistleblower. From that moment, the reporting manager has three months to investigate the report and give feedback and an adequate follow-up to the report. Next, the rules offer strong protection against any retaliatory measures the reporter may experience. Regardless, these rules are mostly intended to offer the necessary protection for whistleblowers and to ensure that companies take necessary investigative steps following a report, but they do not include much information about the actual procedure of the investigation besides certain deadlines, nor do they deal with other employees involved (or under investigation).

In respect of data protection, the processing of personal data in whistleblowing systems is considered by the Finnish Data Protection Ombudsman (DPO) as requiring a data protection impact assessment (DPIA).

The employer should first identify which individuals may have protection as whistleblowers. This could be a current or former employee who raises the initial complaint, a co-worker who gives evidence as part of the investigation, or the accused employee.

In each case, consider whether a “protected disclosure” has been made (under Part IVA ERA 1996). This requires analysis of the subject matter of the disclosure, how it is made, and a reasonable belief that it is made in the public interest.

Employers must then ensure there is no detrimental treatment or dismissal of any worker on the grounds of their protected disclosure. Although the causation test for these purposes is not straightforward, as a general rule if the protected disclosure has a “material influence” on the decision to discipline or dismiss, there may be liability. Individual managers may be personally liable alongside the employer. Compensation for whistleblowing cases is uncapped, meaning businesses and individuals can face significant financial and reputational exposure.

What this means in practical terms is that the employer should promote a “speak-up” culture and, where protected disclosures are made, ensure they are handled by a team who are properly trained in how to do so.

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.

Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.

In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

Concerning a workplace investigation, there is no specific legislation in force at the moment regarding confidentiality obligations. All normal legal confidentiality obligations (eg, obligations outlined in the Trade Secrets Act (595/2018)), and if using an external investigator, the confidentiality obligations outlined in the agreement between the employer and the external investigator, apply. Attorneys-at-law always have strict confidentiality obligations as per the Advocates Act (496/1958).

Workplace investigations should usually be conducted on a confidential basis, so that only those involved in the investigation are aware of its existence and subject matter. The need to maintain confidentiality about both the fact of the investigation, and any content discussed with an investigator, should be emphasised to all those involved. It may also be necessary to explain that a breach of confidentiality could be viewed as a disciplinary matter. Appropriate exceptions must, however, be made to allow employees to speak to any relevant employee or trade union representative, legal adviser and potentially the police or other regulators. Confidentiality provisions cannot override the rights of workers to make protected disclosures (see question 9).

In some situations, such as those involving a wide-ranging investigation into the organisation’s working practices and culture, it may be more appropriate to investigate a more “open” basis, and inform employees and other stakeholders.

In general, the employee should be informed that there is an ongoing investigation (unless this could jeopardise the investigation, in which case disclosure could be postponed until this is no longer the situation). Next, before imposing measures or sanctions, the employee should be allowed to be heard or to give his or her version of the facts. Of course, the employee can only do this if he or she is aware of the facts being investigated. It is not necessary to give the employee a full insight into the investigation, only the necessary facts that allow him or her to offer a defence are sufficient.

The process must be transparent and impartial, and therefore all the information that may influence the conclusions made during the investigation should be shared with the employee.

The employee must be able to effectively challenge the allegations against them. They should be given the terms of reference for the investigation, and any relevant documentary evidence, including copies of witness statements.

If the complainant made use of an internal whistleblowing procedure, confidentiality regarding the identity of a reporter is mandatory. Also, in other cases and for other involved persons (witnesses), it is recommended to keep their identity confidential to prevent the risk of intimidation or other negative consequences.

In complaints due to sexual harassment, violence or bullying at work, if the prevention adviser heard or took written statements from persons that were considered useful for the evaluation, these persons may remain anonymous.

The employee must, nevertheless, receive sufficient information to be able to offer a defence concerning the facts of which he or she is accused.

See question 11, there is no protection of anonymity as the process must be transparent to the parties involved.

Only in exceptional circumstances, such as where there is a genuine risk of retaliation. Anonymising a complaint puts the employee under investigation at a significant disadvantage, as they may be unable to properly challenge the evidence against them. It can also impair the effectiveness of the investigation. Employers should, therefore, not provide any guarantees of confidentiality to complainants or to employees who are to act as witnesses. That said, employers should think carefully about any necessary disclosure of names or facts. This can be particularly relevant where the witness is subordinate to the employee being investigated.

In principle this is possible. However, these NDAs do have their limits and cannot prevent involved persons from, for example, bringing a legal claim or filing a report if they are legally entitled to do so. Under whistleblower rules, a reporter can even publish his or her complaint under certain circumstances.

Yes, however, the need for an NDA is assessed always on a case-by-case basis.

Only to a limited extent. As a matter of law, NDAs cannot prevent a worker from making a protected disclosure, or reporting a crime to the police. As a matter of the regulatory obligations of solicitors, NDAs should not be used in other ways, including as a means of influencing the content of disclosures, or by using warranties, indemnities and clawback clauses in a way that is designed to, or has the effect of, improperly preventing or inhibiting permitted reporting or disclosures (see the SRA’s warning notice on the use of NDAs).

If the investigation is conducted by a prevention advisor, the investigation and the prevention advisor are bound and protected by a professional duty of confidentiality.

The privilege of investigation materials concerns a rather limited amount of cases. In practice, materials may be considered privileged in connection with the litigation process under the Procedural Code (4/1734). For example, communications between a client and an attorney may attract protection against forcible public disclosure.

There are two limited types of privilege which may be relevant to investigations:

• Legal Advice Privilege (LAP), which protects communications between lawyers and their clients provided they are confidential and made for the dominant purpose of obtaining or giving legal advice; and
• Litigation Privilege (LP), which can extend to communications between a lawyer and client or third parties, but only where the dominant purpose of the communication is to prepare for or conduct existing or contemplated litigation.

If the relevant tests for privilege are met and apply to materials generated in the course of the investigation, the employer retains greater control over their subsequent disclosure to third parties. The materials would, for example, be protected against disclosure in any subject access request under the DPA 2018.

That said, privilege can be difficult to maintain in investigations, particularly where litigation is not active or in contemplation. Interview notes and witness statements may not attract privilege, particularly if these were conducted with employees who do not fall within the narrow definition of “the client” for LAP purposes (which is limited to employees who are capable of seeking and receiving advice on behalf of the employer).

If privilege applies to investigation materials, the investigator should keep tight control on what documents are created and how they are circulated, to avoid inadvertent disclosure and potential waiver of privilege.

Bear in mind that even if privilege applies to certain investigation materials, there may be a need to create disclosable documentation at a later stage, particularly if there is a decision to instigate disciplinary action.

An employee can be assisted by a member of a trade union. They are also free to consult a lawyer.

The employee under investigation has a right to have a support person present (eg, a lawyer or an employee representative) during the hearings and a right to assistance in preparing written statements.

There is no statutory right to be accompanied at a disciplinary investigation meeting; the right only applies to disciplinary hearings (section 10 ERA 1999). There is, however, a right to be accompanied by a colleague or trade union representative at any grievance investigation meeting, under section 10, although this is only in respect of the person who raises the grievance (not any person who is the subject of the grievance or other witnesses).

That said, the employer’s policies and contracts should be checked to see if they contain a broader right to be accompanied. Employers may also need to allow a broader right to be accompanied as a reasonable adjustment for disabled employees (for example, to allow family members or medical professionals to be present). Equally, where the allegations are sufficiently serious (eg, criminal, especially if the findings are likely to be shared with the police), it may be appropriate to allow legal representation during the investigation.

At the request of the involved employee, an employee can be assisted by a member of the trade union delegation, for example, during his or her hearing.

The works council should be informed of an investigation if there is a considerable impact on the company; this will only be the case if the investigation concerns a very serious, important or widespread issue. This information should be communicated as soon as possible and before measures are taken as a result of the investigation. This is only a right to information, not consultation. Moreover, members of the works council may be asked to respect their duty of confidentiality. However, as the enforcement of this duty of confidentiality is difficult, the timing of the information should be chosen wisely so it does not jeopardise the investigation.

A works council or a trade union does not have a role in the investigation.

Aside from the statutory right to be accompanied (see question 15), any further involvement by the works council or trade union would depend on the terms of the relevant works council or trade union recognition agreement.

There are no other mandatory support measures. However, an employer is free to offer additional support, for example, by granting leave from work. If tensions at the workplace are high, it may be a good idea to ask the employee under investigation to take some leave. Some companies also provide certain legal, moral or even psychological support. If the complaint concerns sexual harassment, bullying or violence at work, the prevention adviser can also recommend that the employer take additional measures to support certain employees.

Furthermore, under the whistleblower rules, an external reporting authority can grant any support measure (eg, legal advice or financial, technical, psychological or media-related, social support).

For complaints due to sexual harassment, violence or bullying at work, and if the facts are serious, the prevention adviser should, during the examination of the request and before giving his or her opinion to the employer, propose protective measures to the employer. These measures are necessary to avoid serious damage to the complainant's health or a significant deterioration in the situation (for example, causing opposing parties to commit criminal offences). The final decision on taking these measures rests with the employer. This means that the employer does not necessarily have to take the measures proposed by the prevention adviser. They may take other measures that provide an equivalent level of protection for the employee.

They can request assistance, for example, from an occupational health and safety representative, a shop steward or the occupational healthcare provider.

The employer needs to consider the health and wellbeing of all staff involved in the investigation, since this can be a very stressful process. The employer and investigator can assist by ensuring that all parties are aware of what is expected of them. Timings are also important; having a clear and expeditious timetable and providing updates if the timetable slips will help. Regular catch-ups by managers can be used to monitor how employees are coping. They should be reminded about any resources to help support them, such as employee helplines or employee assistance programmes.

Where an employer has particular concerns about an employee’s health, a referral to occupational health can assist. The employer may also wish to consider whether employees should be given additional time off, or whether any other adjustments can be made to the investigation process. For particularly serious allegations, the employer may consider facilitating the provision of independent legal advice for the employee, or making a contribution towards legal fees.

If the investigation is not protected by confidentiality towards the employer (e.g. the prevention advisor cannot disclose confidential information to the employer), it could result in further measures taken by the employer or lead to a new investigation.

If they are related to the work or workplace, the employer will handle the emerging matters separately. In internal investigations, the employer is allowed to use any material legally available.

These should typically be disregarded by the investigator. From a data protection perspective, the ICO’s position is that other information collected during an investigation should be disregarded and, where feasible, deleted unless it reveals information that no reasonable employer could be expected to ignore. In those circumstances, the employer should arrange for an independent third party to determine whether a separate investigation into unrelated matters is needed.

This will depend on where the employee raises a grievance and the content of the grievance. If it is against the employer, the investigation can take this into account and continue from there. If the grievance is raised against the authorities, it will depend on the steps taken by the authorities.

If the nature of the grievance relates to the employer's obligations to handle such matters in general, the grievance will be investigated either separately or as a part of the ongoing investigation.

This is a relatively common tactic. The employer will need to decide whether to suspend the investigation to deal with the grievance, or conclude the investigation first, depending on the circumstances. It would usually be difficult to deal with both the grievance and the investigation concurrently, unless the facts overlap significantly.

If the employee becomes uncooperative and refuses to take part in the investigation, they should be told that the investigator may need to make a decision in the absence of their account based on all the other evidence available. The employer may decide to treat it as failure to comply with a reasonable management instruction and take disciplinary action on that basis.

If this occurs, there is a risk that any measure resulting from the investigation (eg, a dismissal) can be (wrongly) interpreted as discrimination based on the illness of the employee. However, if the employer can prove that the measure is not related to the illness but solely related to the investigation (which is also not related to the illness), there may be no discrimination. The sickness of the employee may prevent the continuation of the investigation because, for example, it becomes impossible to hear from the employee. In this instance, the investigation can be suspended, postponed or extendeded until the employee returns. If it is a long-term absence, this could lead to a disproportionate amount of time to complete the investigation. Therefore, the employer should take any necessary steps to invite the ill employee to a hearing anyway (eg, through digital means). If the employee unreasonably refuses (several) of these invitations, it could be argued that the employee is wilfully boycotting the investigation and therefore forfeits his or her opportunity to be heard.

As a general rule, sick leave does not prevent an investigation from progressing. Depending on the nature of the sickness, the employee can attend hearings and take part in the procedure. If the sickness prevents the employee from participating, the employer can put the process on hold temporarily.

This is a relatively common occurrence. It would usually be appropriate to suspend the investigation temporarily, to determine how serious the health issue is and when the employee may be fit to return. The investigator should consider what adjustments or allowances can be made to progress the investigation despite the employee’s absence. If their evidence has not yet been gathered, the employee may be invited to provide a written statement instead of attending an investigation meeting, or the meeting could be held remotely or at a neutral location. If none of this is possible, it may be difficult to fully conclude the investigation.  

In legal proceedings, a criminal procedure takes precedence over civil procedures. However, disciplinary internal proceedings (like a workplace investigation) and an investigation by the authorities may run parallel to each other. If the public investigation leads to a court procedure that results in the acquittal of the employee under investigation, it could lead to legal problems if the employer has already imposed sanctions based on the same employee. Therefore, the employer could make the internal investigation dependent on the public investigation, and could take preventive measures while awaiting the outcome.

The public authorities normally have the legal competence to request information that can help them in their investigation. Therefore, they could rightfully ask the employer to share evidence or findings from the internal investigation.

Regardless of a possible criminal investigation, the employer must run its internal workplace investigation without unnecessary delay. A workplace investigation and a criminal investigation are two separate processes and can be ongoing simultaneously, so the criminal process does not require the workplace investigation to be stayed. Thus, parallel investigations are to be considered as two separate matters. The police may only obtain evidence or material from the company or employer if strict requirements for equipment searches are met after a request for investigation has been submitted to the police.

This situation needs to be handled with caution. It is important to remember that regulatory or criminal proceedings, and employment proceedings, are separate; while there may be an overlap of alleged misconduct, they are usually addressing different questions, with different standards of proof. The outcome in one should not, therefore, be treated as determinative of the other.

Where the employee is suspected of, charged with, or convicted of, a criminal or regulatory offence, the employer should still investigate the facts as far as possible, come to a view about them and consider whether the conduct is sufficiently serious to warrant instituting the disciplinary procedure.

In terms of timing, there are no concrete rules governing how an employer must proceed in the circumstances of a parallel criminal investigation. Much will depend upon the circumstances of the case, the length of delay, the size of and resources available to the employer, and the preferences (if expressed) of the external authority. If the employer is concerned about prejudicing the regulatory or criminal proceedings or otherwise prefers to wait for their conclusion before instigating internal proceedings, they are unlikely to be criticised for delaying. The accused employee may also be advised not to provide a statement in the workplace investigation for fear of a negative impact on the criminal investigation. This would make it difficult to proceed with the workplace investigation, unless the employer is confident it has strong enough evidence to justify any disciplinary action subsequently taken.

On the other hand, regulatory or criminal investigations may take months or years to progress; it may not be realistic for the employer to keep any investigation in abeyance for so long. This is particularly true when the accused employee is suspended on full pay, witness recollections will grow less reliable, and the alleged victim may feel unable to return to work until the matter is resolved.

In these circumstances, the employer may continue with their investigation if they believe it is reasonable to do so, and consultations have commenced with the external agency. The court will usually only intervene if the employee can show that the continuation of the disciplinary proceedings will give rise to a real danger that there would be a miscarriage of justice in the criminal proceedings.

Employers should consider carefully whether and when to involve the police in allegations of employee misconduct. Employers must be careful not to subject their employees to the heavy burden of potential criminal proceedings without the most careful consideration, and a genuine and reasonable belief that the case, if established, might justify the epithet “criminal” being applied to the employee's conduct.

Where the police are called in, they should not be asked to conduct any investigation on behalf of the employer, nor should they be present at any meeting or disciplinary meeting. The employer should, however, communicate with the police to see if they have a strong view about whether the internal process should be stayed, or whether they should interview witnesses first.

It is highly recommended to inform the employee under investigation of the outcome. If disciplinary measures are imposed upon him or her, the legal procedure must be followed and the sanction must be imposed or communicated the day after the employer or his delegate has established the wrongdoing of the employee.

The employer's conclusions from the investigation.

The employee would usually get a copy of the investigation report (which would typically have the relevant evidence considered by the investigator annexed to the report, unless the report is privileged). It is not usual practice to allow the employee to make representations on the report before it is finalised.

The report will set out what facts the investigator was able to establish by reference to the available evidence. The investigator’s role is to gather and consider evidence about what did or did not happen, so the employer can understand if there is a case to answer. This is distinct from determining culpability, which is something for the manager conducting the disciplinary hearing (not the investigator) to determine, in addition to deciding any disciplinary sanction.

It is recommended to limit the communication to the findings and details of the report that are necessary for the employee to fully understand the outcome. This is especially true if the investigation is bound by a duty of confidentiality (eg, under the whistleblowing rules), as the employee should not be allowed access to the full report.

The employee under investigation may only be informed of the conclusions.

The answer to this depends on whether or not privilege attaches to the report, as well as whether criminal proceedings are contemplated – if so, there may be a danger of waiver of privilege, or witness evidence being contaminated if they have an opportunity to read each other’s evidence as part of the report. This could inhibit the fairness of any subsequent criminal trial.

If the investigation leads to the establishment of grave errors by the employee, this can lead to sanctions. The employer must follow the procedure laid down in the internal work rules of the company and can only impose sanctions that are included in the internal work rules. In general, these are: a verbal warning; a written warning; a suspension (remunerated or not); a fine (capped to one-fifth of daily remuneration); and dismissal. If there are very serious errors leading to an immediate inability to continue the employment relationship with the employee, the employer can dismiss the employee with urgent cause without any notice period or indemnity in lieu of notice (following the specific procedure for these types of dismissals). In less serious cases, the employer could still dismiss the employee with a notice period or indemnity in lieu of notice. In principle, the employer has a right to dismiss the employee, even if this sanction is not included in the internal work rules.

As said previously, disciplinary sanctions (included in the internal work rules) must be communicated to the sanctioned employee the day after the employer or his delegate has established fault. The sanction must be registered in a sanction register, with the name of the employee, the date, the reason and the nature of the sanction. If there is a fine, the amount of the fine should be mentioned. The proceeds of the fines must be used for the benefit of employees. Where a works council exists, the use of the proceeds of the fines must be determined after consultation with it.

The employer decides whether misconduct has taken place or not. Depending on the case, the employer may recommend a workplace conciliation in which the parties try to find a solution that can be accepted by both sides. The employer may choose to give an oral reprimand or a written warning. If the legal conditions are met, the employer may also terminate the employment agreement.

The investigator may recommend further action, but should not decide whether allegations are true, or suggest a possible sanction or prejudge what the outcome of any subsequent disciplinary process would be.

The employer will need to consider whether it is necessary to commence disciplinary proceedings. For regulated businesses, there may be an obligation to inform their regulator of the investigation outcome. In some circumstances, the employer may feel the need to make an internal or external announcement about the outcome, and any action it intends to take to implement any recommendations made by the investigator. There may also need to be certain updates to policies or procedures as a result of the investigation.

If the investigated acts constitute a crime, the authorities or the police should be informed. In certain cases, not doing so could lead to the company being accused of concealing a crime or becoming jointly responsible for it. However, if the company is the only victim of the crime and it is minor, the company may choose not to inform the authorities. For example, there is an enormous difference between a bank employee stealing large amounts of money from clients and an employee who is stealing toilet paper from the company. As stated above, the interview records could be at risk of disclosure if the authorities or police seize them for their investigation.

In general, investigation materials, including findings, that includes personal data should only be processed by the personnel of the organisation who are responsible for internal investigations. However, it may in some situations be required by applicable legislation that findings are disclosed to competent authorities for the performance of their duties, such as conducting investigations in connection with malpractice and violations of the law.

Primarily, the investigation findings are disclosed to the employer and the employee under investigation. In scenarios involving allegations of a breach of regulatory duty or criminal law, the authorities may have the power to compel disclosure of any non-privileged materials generated in the investigation. Powers of compulsion do not apply to privileged materials.

According to the GDPR, personal data should only be stored for a proportionate amount of time. Usually, this means that it can be stored as long as it is relevant for the employment contract, and even afterwards, if there is a risk of legal proceedings (ie, regarding the dismissal of the employee).

Please see question 7. The outcome of the investigation involving personal data may be retained only for as long as is necessary considering the purposes of the processing. In general, the retention of investigation-related data may be necessary while the investigation is still ongoing and even then the requirements of data minimization and accuracy should be considered. The data concerning the outcome of an investigation should be registered to the employee's record merely to the extent necessary in light of the employment relationship or potential disciplinary measures. In this respect, the applicable retention time depends on labour law-related rights and limitations, considering eg, the applicable periods for filing a suit.

The investigation outcome may not need to be noted on the accused employee’s record at all. Usually only the outcome of any subsequent disciplinary or grievance process would be noted, rather than the prior investigation.

The employer should keep the investigation report for as long as it remains relevant. This would usually be no longer than six years, unless regulatory obligations dictate otherwise. The report along with all documentation and witness statements gathered during the investigation should be retained securely and confidentially but for no longer than is absolutely necessary under the requirements of the DPA 2018 and the employer's data protection policies and procedures. There may be additional retention requirements in a regulated context; the position for each particular business and employee should be checked.

In general, abusive investigations could lead to a legal claim regarding the abuse of rights. During an investigation, an employer should be guided by principles of due diligence and not take disproportionate action. If the investigation causes unnecessary damage, involved employees could file for compensation (eg, before the labour court). Next, the employer is also responsible for following the mandatory procedure for official complaints regarding sexual harassment, bullying and violence at work and investigations of whistleblower reports. In the first case, an employer who does not follow the procedure or obstructs the procedure can be liable for penal or administrative fines (maximum 8,000 euro) or, if the employer has not taken necessary measures to mitigate the risks for the employee and the employee suffers damage to their health, they may be liable for a fine of a maximum of 48,000 euro and imprisonment for between six months and three years. In the second case (whistleblower procedure), if an employer did not follow or has obstructed the procedure, they can be fined up to 5% of the annual revenue of the preceding year.

If the complaints involve allegations of sexual harassment, violence or bullying at work, the employer might risk an investigation of the inspection on supervision and well-being at work. If the prevention advisor finds out, before giving his advice, that the employer did not take any suitable protective measures after they were recommended, the prevention advisor is obliged to call an inspection on supervision and well-being at work.

There are no regulations regarding the actual investigation process. Therefore, the employer cannot be accused of procedural errors as such. However, once the matter has been adequately investigated, the employer must decide whether or not misconduct has taken place. If the employer considers that misconduct has taken place, the employer must take adequate measures for remedying the situation. Failure to adequately conduct the investigation could result in criminal sanctions being imposed on the employer as an organisation or the employer’s representative, or damages.

A reasonable investigation is a key component of a fair disciplinary process. Errors in the investigation could therefore expose the employer to liability for unfair dismissal under ERA 1996.

Failure to follow the ACAS Code does not automatically make an employer liable in any proceedings taken against it. However, an employment tribunal will take the ACAS Code into account when deciding whether an employer has behaved fairly, and has the power to increase awards by up to 25% where it believes an employer has unreasonably failed to follow the ACAS Code's provisions.

There may be liability for breach of the employee’s contract of employment if the employer breaches aspects of the investigation policy that are contractual, any contractual provisions relating to suspension, or otherwise conducts the investigation in a manner that breaches the implied term of trust and confidence.

There may be liability under the EA 2010 if the investigation is conducted in a discriminatory manner, which could include not making reasonable adjustments to the process for disabled employees.

Where the investigation involves protected disclosures, there may be liability under the whistleblowing provisions of ERA 1996 if the whistleblower is subjected to detriment or dismissal on the grounds of their protected disclosures.

Improper evidence gathering or processing may be actionable under the DPA 2018, IPA 2016 or the IP Regs 2018.

Finally, there may be common law claims in some circumstances (for example where reports need to be made to regulators, which in turn may affect the relevant employee’s future employment prospects) for defamation, or, more unusually, for stress-related personal injury.
