Workplace Investigations

It is possible to suspend an employee during a workplace investigation.[1] While there are no limits on duration, the employee will remain entitled to full pay during this time.

While an employee is being investigated by the employer, the LPA permits the employer to suspend that employee from work for the duration of the investigation, provided that the suspension can only be made when permitted by the work rules or an agreement related to the conditions of employment. Also, a suspension order must be made in writing and specify the offence and period of the suspension, which may not exceed seven days. Note that the employer must give a written suspension order in advance to the employee before the work suspension.

As aforementioned, the LPA only permits the employer to suspend the employee under investigation from work only for seven days. During the interim period of the suspension, the employer must pay the employee at the rate indicated in the work rules or the agreement reached between the employer and the employee, which must not be less than half of the employee's wages for a working day before his or her suspension. If the employer determines that the employee subject to investigation is not guilty following the outcome, the employer must compensate the employee for outstanding wages from the date of suspension with 15% interest per annum.

In some complicated cases, a workplace investigation does not conclude within seven days, and, in which case the employer should consult with a legal advisor.

In the UK, suspension is not seen as a neutral act, so should not be a default approach at the start of an investigation. It may be appropriate if, for example, there is a risk to the health and safety of the employee in question (or any other employee), a risk that their continued presence in the business could prejudice the investigation, or risk of continued wrongdoing.

The employer should always check the individual’s employment contract to see if it contains the power to suspend. Suspension should generally always be with pay to avoid any breach of contract. It should also be regularly reviewed and kept to a minimum duration.

Employers should not suspend employees under investigation as a knee-jerk reaction to bare allegations. There must be at least some evidence to support the need for suspension (which may require a preliminary investigation before deciding to suspend). Alternatives to suspension should always be considered, such as a temporary transfer to a different area of work, if the employee agrees or it is otherwise permitted by their contract.

If authorities such as regulators or prosecutorial agencies are involved in the investigation, they may have an opinion about an employee’s suspension, particularly if they wish to conduct interviews. Consider whether or not to involve the authorities in the suspension discussions at an early stage.

ACAS have produced a guide to suspension during investigations (last updated Sept 2022) which gives further guidance on these issues.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.

It is down to the employer’s discretion and subject to the whistleblowing policy (if any) to commence the investigation resulting from a complaint from a whistleblower. Whistleblowers and those who cooperate with an investigation should be protected. Normally the employer would not try to identify the whistleblowers. Also, it is best not to reveal the identity of the witness or the source of information; otherwise, they may feel uncomfortable giving information or raising their concerns next time. Any allegations of retaliation that surface during the investigation should be treated as a new report of possible misconduct that could be subject to additional investigation.

The employer should first identify which individuals may have protection as whistleblowers. This could be a current or former employee who raises the initial complaint, a co-worker who gives evidence as part of the investigation, or the accused employee.

In each case, consider whether a “protected disclosure” has been made (under Part IVA ERA 1996). This requires analysis of the subject matter of the disclosure, how it is made, and a reasonable belief that it is made in the public interest.

Employers must then ensure there is no detrimental treatment or dismissal of any worker on the grounds of their protected disclosure. Although the causation test for these purposes is not straightforward, as a general rule if the protected disclosure has a “material influence” on the decision to discipline or dismiss, there may be liability. Individual managers may be personally liable alongside the employer. Compensation for whistleblowing cases is uncapped, meaning businesses and individuals can face significant financial and reputational exposure.

What this means in practical terms is that the employer should promote a “speak-up” culture and, where protected disclosures are made, ensure they are handled by a team who are properly trained in how to do so.
