Workplace investigations are a reactive tool for addressing and resolving issues once they have already likely escalated into a larger problem. Whether it’s a case of sexual harassment, misconduct, or toxic behaviour, early intervention is key to maintaining a healthy and productive work environment.

But how do you know when it’s time to act? As HR professionals, spotting the signs early can save time, resources, and reputations. Here are ten red flags that might indicate the need for a workplace investigation.

What is a workplace investigation?

A workplace investigation is a formal process used to examine allegations of misconduct, harassment, or other workplace issues. It aims to uncover the facts, establish whether policies https://www.telljane.co.uk/what-is-a-workplace-investigation/have been breached, and recommend appropriate actions.

By addressing problems early, organisations can protect their employees, uphold workplace standards, and minimise legal risks.

10 red flags to watch for

1. Increased complaints of unfair treatment

When employees start voicing concerns about favouritism, exclusion, or unequal workloads, it’s a sign to dig deeper. This could indicate broader issues of discrimination or harassment.

2. Unexplained resignations

If valuable team members leave suddenly without clear explanations, it might be worth exploring. Employees often leave toxic environments before formal complaints are made.

3. Persistent rumours

Workplace gossip can sometimes highlight underlying issues. While not every rumour warrants a full misconduct investigation, repeated whispers about inappropriate behaviour or harassment shouldn’t be ignored.

4. Formal grievances

Receiving a formal grievance is a clear red flag. Allegations involving sexual harassment, bullying, or other forms of misconduct require a thorough investigation to ensure fairness and compliance.

5. Decline in team morale

A noticeable drop in employee morale, rising absenteeism, or disengagement can point to deeper problems such as toxic behaviour or harassment in the workplace.

6. Inappropriate third-party interactions

Toxic behaviour isn’t always confined to employees. Complaints about third-party misconduct—such as inappropriate comments or behaviour from clients or contractors—should be taken seriously and investigated promptly.

7. Escalating conflicts

Disagreements between employees are common, but when conflicts escalate or recur frequently, they may be symptomatic of harassment, bullying, or broader cultural issues.

8. Inconsistent performance patterns

Sharp declines in individual or team performance can sometimes indicate that employees are working in an environment affected by misconduct or harassment.

9. Unusual patterns in complaints

If multiple employees raise concerns about the same person, process, or behaviour, it’s a sign that a workplace investigation may be necessary. Patterns often reveal systemic problems.

10. Reluctance to speak up

Silence can be as telling as complaints. If employees hesitate to voice concerns or raise issues, it may indicate a lack of trust in the organisation’s ability to address workplace misconduct effectively.

Why early intervention matters

Ignoring these red flags can lead to far-reaching consequences, including reputational damage, legal liability, and a loss of employee trust. Sexual harassment investigations, in particular, require careful handling to ensure compliance with UK laws and to protect all parties involved.

By acting quickly and conducting fair, thorough workplace investigations, HR professionals can create safer, more inclusive workplaces and avoid long-term damage.

Workplace investigations are not just about addressing complaints—they’re about prevention and maintaining a culture of respect and accountability. As an HR professional, recognising these red flags can help you protect your organisation and its people.
