Workplace Investigations

In Greece, workplace investigations are not heavily regulated.

However, internal disciplinary procedures are governed by certain general principles, while there is also legislation regulating certain aspects of investigations opened in the context of whistleblowing procedures or concerning complaints for workplace violence or harassment. These include Law 4990/2022, which transposed EU Directive 2019/1937 into Greek Law; and Law 4808/2021, which ratified the ILO’s Violence and Harassment Convention, 2019 (No190) and introduced relevant provisions.

As far as disciplinary procedures in private-sector companies are concerned, employers that must have internal labour regulations in place (ie, those with more than 70 employees) or opt to adopt them voluntarily, can regulate the procedures themselves.  

In the public sector, internal investigations are governed by disciplinary provisions included in the civil servant code.

A workplace investigation is usually governed by the employer’s internal grievance policy or contractual guidelines found in the employment contract or employee handbook. In the absence of the same, the default governing regime is as set out by the Ministry of Manpower (MOM) and the Tripartite Alliance for Fair and Progressive Employment Practices (TAFEP) in its guidelines and advisories, which include:

• the Tripartite Advisory on Managing Workplace Harassment;
• the TAFEP Grievance Handling Handbook; and
• the Tripartite Guidelines on Fair Employment Practices.

In addition, section 14(1) of the Employment Act 1968 provides that an employer is required to conduct “due inquiry” before dismissing an employee covered under the Employment Act 1968 without notice for misconduct. The Singapore Courts take the view that “due inquiry” suggests some sort of process in which the employee concerned is informed about the allegations and the evidence against him or her so that he or she has an opportunity to defend him or herself with or without evidence during the investigation process.

Further, there are numerous cases where the Singapore High Court has alluded to or implicitly accepted the application of the implied term of mutual trust and confidence in employment contracts that would oblige the employer to act reasonably and fairly during the investigation, even though it is worth noting that the Singapore Court of Appeal has stated that the status of the implied term of mutual trust and confidence has not been settled in Singapore and that the Appellate Division of the Singapore High Court has stated that “[i]t remains an open question for the Court of Appeal to resolve in a more appropriate case, ideally with facts capable of bearing out a claim based directly on the existence of the implied term” (see [81]-[82] of Dong Wei v Shell Eastern Trading (Pte) Ltd and another [2022] SGHC(A) 8).

Hence, any references to the application of the implied term of mutual trust and confidence in Singapore in this article must be read in light of the above.

The current position is expected to change in the second half of 2024, with the passing of Singapore’s first workplace fairness law, the Workplace Fairness Legislation. On 4 August 2023, the Singapore government announced that it has accepted the final set of recommendations by the Tripartite Committee on Workplace Fairness in respect of the upcoming Workplace Fairness Legislation. The Tripartite Committee on Workplace Fairness recommended, among other things, that employers are required to put grievance-handling processes in place. It is therefore expected that the Workplace Fairness Legislation may contain requirements on how and when a workplace investigation should be conducted.

This article sets out the current position, before the Workplace Fairness Legislation was enacted, and will be updated when appropriate.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

In principle, the health of an ordinary employee would not prevent the investigation procedure from taking place (eg, interviews with witnesses or the collection of evidence would not be postponed or suspended). However, if the employee under investigation is unwell and they can't participate in the procedure, the investigation may be suspended or postponed until the employee can take part. Bearing in mind the majority of company internal policies and regulations governing workplace investigations provide for a specific framework and timetable for the whole procedure to be completed, the long-term sickness of an employee under investigation may impede the completion of the procedure in the prescribed time. As a result, the person conducting the investigation may seek alternative measures to facilitate participation (eg, teleconferencing).

On a related note, if sickness occurs after the investigation is completed and the employer decides upon the imposition of disciplinary measures against the said employee and the initiation of a relevant procedure, the decision should be duly and timely communicated to the employee, irrespective of whether his or her presence in the workplace is not possible because of the illness.

If the employee under investigation has already responded to the allegations made against him or her and his or her participation is no longer required at this stage in the investigation, the employer may proceed with the investigation even while the employee is off sick.   

However, if the employee under investigation has not responded to the allegations made against him or her and his or her participation is still required in the investigation, the company may exercise its discretion to pause the investigation until the employee can assist in the investigations.  To prevent an employee from using a medical condition as an excuse to delay or avoid the investigation, the company may require the employee to provide specific medical documentation to address the issue of the employee’s ability to participate in the investigation and to adjust the investigation process accordingly. For instance, instead of scheduling an in-person interview, the company may send a list of written questions for the employee to answer, and may also extend timelines for responding, etc.   

If the employee is unable to return to work for the foreseeable future, the employer may consider reaching a provisional outcome based on the available evidence, which would be subject to change when the employee under investigation can return to work.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).
