Workplace Investigations

Investigations can start in multiple ways. They usually stem from an employee raising a grievance, a bullying complaint, or a possible protected disclosure. Investigations may also stem from the employer in a disciplinary context, or indeed can be commenced if an external complaint or issue is raised by a third party of the organisation.

The first thing the employer must consider is whether an investigation is necessary. It may be that the issue at hand can be resolved informally or is of such a nature that it cannot be investigated, either through a lack of detail or simply because the subject of the complaint is no longer an employee. Any such decision to investigate or not should be carefully documented.

The next step to determine is the nature of the investigation. It should be clear at the outset whether the investigation is simply a fact-gathering exercise or if the investigator will be tasked with making findings on the evidence. The distinction is significant as a fact-gathering investigation can proceed without prompting the full panoply of rights, but the basic principles of fairness should still be applied. A fact-gathering investigation should determine whether there is or is not, a case to answer. If a disciplinary hearing follows then the rights outlined in question 1 will apply at that stage. If it is a fact-finding investigation, the rights apply from the outset of the process. The employee who is required to respond to the issues (the respondent) should be fully aware of the extent of the investigation. The investigator appointed to do the investigation should be clear about what is expected of them.

If the employer believes an investigation is necessary, it should be acknowledged and started without delay. In particular, according to the Protected Disclosures legislation, a report should be acknowledged within seven days.

An employer should consider and identify the scope of the investigation and establish who will investigate the matter. Terms of reference under which the investigation will be carried out should be established by the employer and shared with the employee raising the issue (the complainant). An employer should not seek agreement on the terms, but invite commentary to ensure that the full scope of the investigation is captured within the terms of reference. Robust terms of reference that lay down the clear parameters of the investigation will assist the investigator and all parties involved in the process.

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]

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.
