Workplace Investigations

A workplace investigation will generally be triggered by an employee making a complaint; however, issues may also be brought to the attention of an employer through an anonymous tip, by suppliers or contractors, from customers or because of observations and hearsay.

Complaints can be made directly to Human Resources (HR), anonymously, by email to a line manager or a third party. While complaints do not need to be written and can be informal, brief or verbal, complaints of this nature can make the process harder and more information may be required.

The receipt of a complaint does not necessarily mean that an employer needs to undertake an investigation immediately. A grievance policy ordinarily contains a multi-step approach to dealing with complaints, starting with internal resolution options such as informal discussions, conciliation and mediation. However, an investigation should be commenced where:

• the complaint alleges serious misconduct or unlawful conduct;
• the employer is required to conduct a workplace investigation as per an employment contract, policy, procedure or industrial instrument; or
• the complaint is complex and requires clarity on what has occurred to establish the facts.

Internal investigations can be initiated either upon a complaint or report by an employee, (or other persons providing services or seeking employment, etc) in the workplace or by the employer as part of their managerial right.

If from an employee, the complaint or report may fall within the scope of an internal disciplinary procedure, if any, or may concern an alleged workplace violence or harassment incident, or fall within the scope of L.4990/2022 on the protection of persons who report breaches of Union law.  

Reports by whistleblowers are submitted to the manager with responsibility for receiving and monitoring reports, a person appointed for that purpose under L.4990/2022. Complaints for incidents and harassment in the workplace can also be submitted, according to L.4808/2022, to the person or internal body specifically assigned to receive such complaints. Both laws require the employer to define the persons competent for receiving and monitoring complaints or reports and notifying the employees stricto sensu and any other persons falling within the scope of the respective provisions.

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

It is not uncommon for respondents to an investigation to take personal or carer’s leave (sick leave) claiming that they are suffering from stress or anxiety. If this occurs, employers need to act appropriately, but this does not necessarily involve stopping the investigation process.

Employers should:

• assess the medical evidence to ascertain the respondent’s condition and determine how long they are likely to be unwell;
• avoid exacerbating the condition;
• determine whether the employee is unfit to attend the investigation meeting;
• take into consideration the evidence of other witnesses;
• consider delaying the investigation for a short period; and
• consider conducting the interviews in other ways, for example, in writing.

While all efforts should be made to accommodate an employee who has taken personal or carer’s leave during an investigation, if the respondent does not participate in the investigation, the investigation report may be prepared based on the available evidence.

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.

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).
