Workplace Investigations

It is an important consideration as to whether any of the employees involved in the investigation should be suspended, stood down or asked to undertake alternative duties for the period of the investigation. This decision will need to be made taking into consideration the nature of the complaint, any further damage to workplace relationships that could be caused by employees continuing to interact with each other, and potential work, health and safety issues.

It should not be automatic that the respondent is suspended as the employer will need to consider whether this is necessary in the circumstances. However, a period of suspension should be considered where:

• the allegations involve serious misconduct;
• there is a risk that the conduct will continue throughout the investigation;
• the respondent’s presence could exacerbate the situation; or
• the respondent’s presence could be disruptive to the investigation.

As an alternative to suspension, other options include working from home, performing amended duties or moving to a different workspace.

If an employee is suspended then they should ordinarily receive their full pay for this period. There are some exceptions to this, for example, if the employee is a casual employee or if a policy, employment contract or other industrial instrument allows the employee to be suspended without pay.

Generally, there is no minimum or maximum period a suspension should last, as this will depend on the length of the investigation.

Workplace suspensions in Ireland are a contentious issue and can result in an employer defending injunction proceedings in the High Court before an investigation has started.

In the case of Governor and Company of the Bank of Ireland v Reilly, the judge stated: “The suspension of an employee, whether paid or unpaid, is an extremely serious measure which can cause irreparable damage to his or her reputation and standing."

In the 2023 case of O’Sullivan v HSE, the Supreme Court held that the Health Service Executive acted fairly and reasonably as an employer in suspending a consultant doctor after he had performed experiments on patients without their consent. This ruling overturned the Court of Appeal's earlier decision that previously found the suspension to be unlawful, as the consultant did not represent an immediate threat to the health of patients.

The Supreme Court considered whether the employer's decision to place the consultant on administrative leave met the test set out in the English case of Braganza v BP Shipping Limited & Anor. In that case, the court held that the decisionmaker's discretion would be limited "by concepts of good faith, honesty and genuineness and the need for absence of arbitrariness, capriciousness, perversity and irrationality."

In relying on the principles set out in the Braganza case, the Irish courts have reinforced the right of a decision-maker in an employment context to have discretionary power when implementing a suspension and that any decision to do so must be made honestly and in good faith. Employers should obtain legal advice when considering whether to suspend an employee in any circumstance.

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.

Confidentiality protects the interests of the persons involved in the investigation as well as the integrity of the investigation. Before providing information as part of the investigation, employers should direct the complainant, respondent or witnesses to sign confidentiality agreements. This agreement should direct the person to refrain from discussing the investigation or matters that are the subject of the investigation with any person other than the investigator.

It is also best practice for participants in the investigation to be directed not to victimise (threaten or subject to any detriment) any persons who are witnesses to or are otherwise involved in the investigation.

After an investigation, employers should write to the complainant, respondent and any witnesses reminding them of their ongoing confidentiality obligations.

This will depend on the nature of the investigation but, generally, investigations should be conducted on a confidential basis. All who participate in the investigation should be informed and reminded that confidentiality is a paramount consideration taken very seriously. However, it should be borne in mind that confidentiality cannot be guaranteed by an employer as the respondent in an investigation is entitled to know who has made complaints against them. Furthermore, the respondent is entitled to cross-examine the complainant and any witnesses, although in practice this right is rarely invoked strictly and is facilitated by the investigator, with questions from the respondent being put to the complainant and other witnesses.

On occasion, a breach of confidentiality may warrant disciplinary action, but this will depend on the circumstances. Exceptions to the requirement to keep matters confidential will of course apply where employees seek support and advice from others such as companions, trade union representatives or legal advisors. It may also not be possible to maintain confidentiality where regulators or the authorities are informed of the investigation.

Also, confidentiality may not be maintained if it is in the interests of the employer to communicate the complaint and any subsequent investigation, for example on a health and safety basis.

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]
