Workplace Investigations

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.

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.

Thai labor laws do not require a workplace investigation to involve participation from trade unions or labour unions. However, it is possible for labour unions established under the Labor Relation Act BE. 2518 (1975) to submit a demand for a collective bargaining agreement (CBA) with employers to get a seat at the table. There was a case where a management union made a CBA with the employer wherein the president of the management union would be involved in any investigation of any manager, who is a union member, under investigation. In that case, the employer must comply with the CBA by informing the president and allowing the president to participate in the investigations.

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.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]

There is no period required by law for keeping the outcome of the investigation on the employee’s record. However, if termination of employment is the outcome of the investigation, an employer should keep details of the investigation for at least 10 years, in line with the prescribed period for an employee to file an unfair dismissal claim against an employer. An employer may use the details of an investigation to defend such a claim. For other disciplinary action, the retention of investigation details on the employee’s record is at the employer’s discretion.
