Workplace Investigations

The circumstances in which an employer commences a workplace investigation may vary. However, it is common that an employer will consider it necessary to commence a workplace investigation upon receipt of a complaint concerning a fellow employee. Sometimes, the complaint may be made anonymously. If the employer considers there to be substance in the complaint, it may commence an investigation to find out the truth of the matter, resolve the complaint and, if necessary, improve its systems and controls to prevent the reoccurrence of any misconduct.

A workplace investigation may be warranted if the employer receives an enquiry from a regulator concerning its affairs or an employee’s conduct. The investigation findings could enable the employer to respond to the regulator (which could be a mandatory obligation) and at the same time assess its risk exposure.

Having been informed of an alleged infraction committed by an employee, the employer must prepare a detailed written accusation and notify the employee.

Moreover, if the alleged infraction constitutes gross misconduct and the employer is considering dismissal, a formal statement of the employer’s intention to dismiss the employee should accompany the accusation. If this is not expressly done, the employer will be unable to dismiss the employee and may only apply one of the conservatory sanctions. A copy of these documents must be sent to the works council, if any, and, should the employee be a union member, to the respective trade union.

Notwithstanding this, if before preparing the accusation the employer needs to further investigate the facts and circumstances, it may open a preliminary investigation aimed at collecting all the facts and circumstances and conclude if there are grounds to bring an accusation against the employee.

The preliminary investigation must start within 30 days of the employer becoming aware of the facts, be diligently carried out (but with no maximum period laid down by law) and concluded within 30 days of the last investigatory act. Furthermore, the preliminary investigation will suspend the relevant statutory deadlines and statutes of limitations (ie, 60 days from the date of acknowledgment, by the employer or a supervisor with disciplinary power, of the facts to enforce disciplinary action against the employee and one year from when the facts occurred, regardless of the employer’s acknowledgment, unless the infraction also constitutes a criminal offence, in which case the longer statutes of limitation established in criminal law will apply).

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 may be appropriate to suspend an employee during a workplace investigation, for instance, where the investigation has revealed misconduct on his or her part (even on a preliminary basis), or his or her continued presence in the business would hinder the progress of the investigation. However, the employer will have to consider the relevant legislative provisions and the terms of the employment contract before making any decision on suspension.

Under section 11 of the EO, an employer may suspend an employee without pay pending a decision as to whether the employee should be summarily dismissed (up to 14 days) or pending the outcome of any criminal proceedings against the employee arising out of his or her employment (up to the conclusion of the criminal proceedings). If an employee is suspended as above, however, the employee may terminate his or her employment without notice or payment in lieu of notice.

It is more common for an employer to suspend an employee with pay during an investigation concerning his or her conduct rather than exercising its statutory right as mentioned above. This could avoid an unnecessary dispute with the employee concerned. Indeed, it is common for employers to include in employment contracts specific provisions to give themselves the right to suspend an employee with pay in certain circumstances. The provisions normally set out the circumstances in which the employer may exercise the right, the maximum period of suspension and other arrangements during the suspension period (eg, how the employee’s entitlements under the employment contract are to be dealt with).

After the employee is notified of the accusation, the employer may decide on a preventive suspension of the employee if the employee’s presence on company premises is deemed problematic. In this case, the employee’s salary will continue to be paid.

As per article 330(5) of the Portuguese Labour Code, a preventive suspension may also be determined during the 30 days before the accusation is made, provided that the employer, in writing, justifies why is necessary (eg, for interfering with the inquiry) and why the accusation cannot be served at that moment.

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.
