Workplace Investigations
Contributing Editors
Workplace investigations are growing in number, size and complexity. Employers are under greater scrutiny as of the importance of ESG rises. Regulated industries such as finance, healthcare and legal face additional hurdles, but public scrutiny of businesses and how they treat their people across the board has never been higher. Conducting a fair and thorough workplace investigation is therefore critical to the optimal operation, governance and legal exposure of every business.
IEL’s Guide to Workplace Investigations examines key issues that organisations need to consider as they initiate, conduct and conclude investigations in 29 major jurisdictions around the world.

Due to the employee's duty of loyalty towards the employer and the employer's right to give instructions to its employees, employees generally must take part in an ongoing investigation and comply with any summons for questioning if the employer demands this (article 321d, Swiss Code of Obligations). If the employees refuse to participate, they generally are in breach of their statutory duties, which may lead to measures such as a termination of employment.
The question of whether employees may refuse to testify if they would have to incriminate themselves is disputed in legal doctrine.[1] However, according to legal doctrine, a right to refuse to testify exists if criminal conduct regarding the questioned employee or a relative (article 168 et seq, Swiss Criminal Procedure Code) is involved, and it cannot be ruled out that the investigation documentation may later end up with the prosecuting authorities (ie, where employees have a right to refuse to testify in criminal proceedings, they cannot be forced to incriminate themselves by answering questions in an internal investigation).[2]

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).

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]
It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).
It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

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).
