Workplace Investigations

Spain has not passed any statutes, regulations or policies specifically governing workplace investigations. Instead, general employment and data protection legislation, which safeguards employees’ rights, is fully applicable during these types of enquiries.

These statutes focus on employee privacy. As a result, the application of this legislation:

• limits the matters that may be investigated: they have to be relevant to the employment relationship and there has to be a legitimate reason to conduct the enquiry;
• sets boundaries to the means that may be lawfully used by the company in the investigation: they must be the least intrusive means for employees’ rights (for instance, an email review should be a last resort, reserved for when less-invasive means are not available or would not be effective); and
• states that the companies’ decisions during the investigation must be proportional in light of the facts under review and the legal consequences attached to them.

Collective bargaining agreements, which in Spain generally apply to every company within their scope of application (normally a given economic sector), may regulate workplace investigations. However, it is unusual for collective bargaining agreements to regulate workplace investigations.

Finally, major international corporations with a presence in Spain do tend to have an ethics or whistleblowing policy that governs how an investigation should be conducted. Even if these are self-imposed policies, they are contractually binding and, once established, must be respected by companies.

Given that Spain lacks legislation in this area (see question 1), each company commences workplace investigations following its internal guidelines, policies or practices, if any. In our experience, investigations begin with a formal decision to commence the enquiry, which is set out in writing for record-keeping purposes.

This decision will normally mention:

• the facts that will be investigated;
• the reasons to investigate the facts (eg, they could be a breach of company policies);
• how the investigation will be conducted; and
• the individuals who will conduct the enquiry.

Depending on the company, the decision to initiate the investigation may take the form of a decision by the competent employee or officer (ethics or compliance officer) or the minutes of the relevant corporate body (board of directors or compliance committee).

Yes, a company may suspend an employee if it has valid grounds to believe that keeping an employee under investigation in his or her position during the enquiry could obstruct the investigation or become an obstacle to it (for example, the employee could try to conceal facts or influence other employees within the organisation).

The decision to suspend the employee must be communicated in writing. This will usually take the form of a suspension letter that explains the reasons that have led to the suspension, its expected duration and that the suspension is not a disciplinary measure. Since the suspension is not a disciplinary measure, the employee would be entitled to continue collecting his or her standard remuneration during the suspension.

In Spain, employees have the right to be effectively occupied during their employment. Therefore, the duration of the suspension should be limited in time to what is strictly necessary to avoid what led to the suspension in the first place.

As set out in question 1, workplace investigations must be proportional and companies must use the least intrusive means to affect employees’ rights. This translates into the following principles on who conducts the investigation:

• the enquiry must involve a minimal number of employees;
• only those employees with competencies on the investigated matters should be involved (normally human resources or compliance); and
• employees conducting the investigation must be qualified and have the power and seniority to do so proficiently (although a formal qualification is not required).

No, an employee under investigation has no direct legal option to stop an investigation. This is because conducting an enquiry is within the employers’ legally acknowledged powers, attached to their capacity to manage their business and enforce employment contracts and internal policies.

Notwithstanding the above, if the investigation breaches an employee’s rights (privacy, dignity, remuneration, etc), the individual could:

• file a lawsuit aimed at stopping said breach (and potentially seeking an award for damages); or
• file a claim with the Labour Inspectorate with the same purpose.

The result, in this case, would stop the enquiry.

A company cannot force an employee to actively take part in a workplace investigation or to act as a witness. However, if a co-worker’s decision not to collaborate could be construed as an attempt to conceal evidence of wrongdoing, the company could then enforce disciplinary measures for this reason.

In our experience, employees tend to collaborate during workplace investigations and no retaliatory action can be taken against them for this reason. For example, if an employee provided evidence against his or her direct manager, the manager could not reprimand the employee or take any action that could be construed as such.

The General Data Protection Regulation and the Spanish Data Protection Law apply when gathering any type of evidence, including physical evidence. This means that companies may only process personal data when they have lawful grounds to do so and within the limits set forth for special categories of personal data (health, union affiliation, criminal records, etc.).

The Spanish Statute of Workers specifically states that employees and their possessions may be registered when it is necessary to protect the companies’ property (or the property of other co-workers). This registration must:

• be conducted in the workplace and during working hours;
• respect the employee’s privacy and dignity; and
• be performed in front of an employee representative or, if not possible, in the presence of another employee of the company.

Please see question 7.

Directive (EU) 2019/1937 of the European Parliament and of the Council, of 23 October 2019, on the protection of persons who report breaches of Union law, has been implemented in Spain through Law 2/2023 (Ley 2/2023, de 20 de febrero, reguladora de la protección de las personas que informen sobre infracciones normativas y de lucha contra la corrupción). This law limits the capacity of companies to retaliate or to take any action against employees who report workplace violations or breaches of the law. Any action taken against an employee in such a position would be considered null and void if challenged in court.

Spanish law allows anonymous reports to protect whistleblowers from retaliation.

Companies and employees are not bound by any statutory confidentiality obligation in the context of workplace investigations. However, if a company’s enquiry has the potential to examine employees’ private affairs, then the company must ensure the confidentiality of the investigation.

This confidentiality obligation would not arise from the investigation itself, but from the company’s obligation to safeguard its employees’ rights.

It is not necessary to inform an investigated employee about an enquiry or of the allegations made against him or her. The obligation to disclose would only arise when:

• interviewing the employee would be the least intrusive means to investigate the facts; or
• if disciplinary measures are implemented as a result of the investigation. Since employees are entitled to challenge all disciplinary measures against them, they could request a court of law to disclose all the findings of the investigation, to assess if these findings could be useful to challenge the disciplinary measure.

As in question 10, the identity of the complainant or other employees involved in the investigation may be kept confidential and companies do not have to share their identity with investigated employees. Anonymous complaints are expressly allowed under Spanish law (see question 9).

Companies may have to produce this information and share it with the investigated employees if it is necessary to allow them to defend themselves from disciplinary measures taken against them. Similarly, in the context of litigation, an employee or plaintiff could request a Labour Court to order the company to disclose the details of the investigation.

Yes. NDAs are the preferred instrument to ensure that employees conducting the investigation, as well as those who participate as witnesses or collaborators, will keep the enquiry and its existence confidential.

As explained above, investigation materials are not protected by privilege per se. To protect the confidentially of these materials, it is advisable to enter into NDAs with the employees involved in the investigation.

A workplace investigation under Spanish law is a fact-finding exercise and not a disciplinary procedure. For this reason, employees are not entitled to representation during an investigation (it is not even necessary to inform them about the enquiry).

If the investigated employees are made aware of the investigation (eg, because they will be interviewed or questioned), then it is good practice to allow them to be accompanied by external counsel or an employee representative. This would reduce the risk that employees would claim that they were under duress during the interview, or that they challenge the validity of the evidence obtained by the company.

As explained in question 15, employees are not entitled to representation during an investigation. However, if a disciplinary procedure starts as a result of the investigation, employee representatives may be entitled to be informed of the disciplinary procedure and its outcome.

The degree and timing of when employee representatives must be involved will depend on several factors such as:

• the employee’s affiliation to a union;
• if the employee is an employee representative;
• the seriousness of the potential sanction to be imposed; and
• the information rights that the applicable collective bargaining agreement acknowledges regarding employee representatives.

For the reasons outlined in question 15, companies sometimes choose to voluntarily provide support to employees involved in the investigation (to ensure that evidence was lawfully obtained during the interview and is valid).

For investigated employees, one available support mechanism is for the company to cover the legal fees of an external counsel during the investigation or to offer to involve employee representatives. Reassurance may be provided to witnesses by guaranteeing, in writing, that their involvement in the investigation will be kept confidential and will not result in a detriment.

The issue with revealing unrelated matters to the investigation is that it may jeopardise the entire enquiry. If the unrelated matters are private or the disclosure is construed as a breach of employees’ fundamental rights, then the materials gathered during the investigation could be considered to be unlawfully obtained and would not be admitted as evidence in court.

Moreover, the employee could seek damages and a fine could be imposed on the company for breaching its employee’s rights.

Finally, if unrelated matters are revealed, it could be a clear sign that the company has failed to conduct a diligent investigation and use the least intrusive means available to it (see question 1). One of the reasons to minimise the number of employees conducting the investigation (see question 4) is to reduce damages if matters unrelated to the investigation are revealed.

Spanish law does not regulate grievance processes and most companies do not have an internal grievance procedure. The only way in which an employee can formally challenge an investigation is by filing a lawsuit or lodging a claim with the Labour Inspectorate (see question 5).

To the extent that the company can show that the investigation is unrelated to the complaint (ie, that the investigation is not retaliation for filing the complaint), the claim should be seen as neutral from the perspective of the enquiry.

Like in the case of grievances (see question 19), the deciding factor will be assessing whether sick leave is related to the investigation or not.

If there is no link between the investigation and the sick leave, then the leave is not relevant from the point of view of the investigation. However, if the sick leave was a result of the investigation (for instance, an employee taking sick leave due to anxiety related to the investigation), then the convenience of pursuing the investigation or of temporarily suspending it should be evaluated to avoid any liability for the company.

Criminal or regulatory investigations may (and usually do) run in parallel to workplace investigations.

There is no need to stay the internal investigation and, in practice, this normally is not possible or advisable considering the substantially longer timeframe of criminal or regulatory investigations (which can extend for several months or years).

The police or a regulator may request a company to share any relevant information that it might have on the facts being reviewed by them. However, the company’s obligation to provide that information would have to be reviewed on a case-by-case basis, depending on the information being requested (eg, whether it is sensitive to the business, such as trade secrets or internal correspondence) and the grounds to do so (if the police or regulator have a search warrant issued by a court or not).

Employees under investigation are not entitled to be informed about the investigation or its outcome. As set out above (see question 11), an employee would have a right to be informed about the outcome of an investigation if the employer takes any disciplinary actions as a consequence of the enquiry.

The reason to disclose the details of the investigation is to allow the employee to adequately defend him or herself from the alleged breaches.

Since workplace investigations are not regulated in Spain, there are no clear rules as to the amount of information on the investigation that would need to be shared with an employee if the company was compelled to disclose the enquiry (see questions 11 and 22). A good rule of thumb is that an employee should have access to all the information that is relevant to be in a position to oppose the alleged breaches.

Moreover, if the disciplinary measures taken were challenged before a Labour Court – employees in Spain tend to challenge these types of measures – the plaintiff could request the Labour Court to order the company to produce all of the investigation details, including the findings and the full investigation report.

Finally, companies will normally have an interest in producing a report that clearly states the moment in which the fact-finding exercise was concluded and the company had a full picture of the facts. This is because the statute of limitations to sanction employment breaches, which ranges from 10 to 60 days depending on the seriousness of the misconduct, starts to count when the company has a comprehensive view of the events (which would coincide with the date the investigation report was issued).

After the conclusion of the enquiry, a company may choose to:

• close the investigation without taking any additional action; or
• adopt disciplinary measures against the employee.

These could range from a verbal or written warning to the suspension of work and pay for a set period. Disciplinary dismissals are also possible, but they are reserved for very serious offences.

Note that any disciplinary measure will have to follow the procedures that might be established in the applicable collective bargaining agreement, such as informing employee representatives or following a grievance procedure before adopting the measure.

Companies may only disclose the outcome of an investigation to employees or officers of the company who are empowered to adopt the measures that are necessary because of the investigation’s results (see question 4).

This disclosure obligation does not extend to authorities: while there is a general obligation to report criminal or administrative offences to the competent authorities, this obligation must be read in line with the companies’ right not to self-report themselves. What a company must not do is cover up, aid or otherwise become an accessory to the offence.

The outcome of the investigation will contain personal data of the affected employee. For this reason, this information should only be kept for as long as a legal obligation or liability in connection with the information could arise for the company. Since the general statute of limitations for employment liability is one year, this is a good guideline.

In addition to the above, two specific rules apply:

• once the information becomes irrelevant for the purpose for which it was obtained and processed, the information should no longer be stored on the employee’s record or elsewhere; and
• the employees’ information (including those of the reporter and the affected employees) should only be stored in whistleblower systems during the time that is necessary to decide on whether the facts need to be investigated or not and, in any case, for a maximum period of three months.

Errors during an investigation are normally linked to the breach of the employees’ privacy or their personal data rights (see question 1). Breaching these rights might expose employers to:

• Fines from the Labour Inspectorate and the Spanish Data Protection Authority.
• A court awarding damages to the employee.
• Any disciplinary measures adopted by the company as a result of the investigation could be considered null and void.
• The evidenced obtained during the investigation being disregarded by a court.
• In some very serious cases, criminal liability might arise for the individuals who conducted the investigation and breached the employees’ rights.
