The first few decisions can shape everything that follows.
A grievance does not automatically mean the business has done something wrong. But a poorly handled response can turn a manageable workplace issue into a much bigger Employee Relations problem.
There is no legal “48-hour rule” — but acting promptly, calmly and methodically matters.
Here is what I would focus on first.
1. Understand exactly what has been raised
Do not immediately jump to conclusions or start interviewing people.
Read the grievance carefully.
What are the actual allegations?
Who is involved?
What outcome is the employee seeking?
Does it involve bullying, discrimination, harassment, whistleblowing, health concerns or allegations against senior management?
The answers will determine how the matter should be handled.
2. Acknowledge it promptly
The employee should know their grievance has been received and will be considered.
Avoid giving an instant view on the merits.
Something as simple as confirming receipt, explaining the next step and giving an indication of when they will hear from you again can prevent unnecessary escalation.
3. Consider whether immediate action is needed
Some grievances can wait for the normal process.
Others cannot.
For example:
• Is anyone potentially at risk?
• Could evidence disappear?
• Is the employee still reporting to the person they have complained about?
• Is there a risk of retaliation or further conflict?
• Does anyone need temporary support or alternative reporting arrangements?
Any interim measures should be proportionate. Suspension or removing someone from their role should not be an automatic response.
4. Preserve the evidence
Emails, Teams or Slack messages, CCTV, documents, meeting notes and other records may become important.
If there is a possibility that relevant evidence could be deleted or overwritten, preserve it early.
This is often overlooked until much later in the process.
5. Decide who should handle the grievance
Independence matters.
If the grievance concerns the employee’s manager, HR, a director or someone senior within the organisation, simply passing it to the next available manager may not be appropriate.
Ask:
Does this person have the independence, experience and authority to deal with the allegations fairly?
For particularly serious or sensitive matters, an independent investigator may be the safer option.
6. Define the scope before investigating
One of the biggest mistakes in workplace investigations is starting without being clear about the questions that actually need answering.
A good investigation should establish the relevant facts.
It should not become an unlimited search through every disagreement the employee has ever had with the business.
Clear allegations.
Clear scope.
Clear evidence.
That makes the eventual decision far easier to defend.
7. Do not treat the grievance as an inconvenience
The worst response is often a defensive one.
Trying to dismiss the complaint quickly, attacking the employee’s credibility before investigating, or assuming that a long-serving manager “would never do that” can create additional risk.
The purpose of the process is to establish what happened and reach a fair, evidence-based conclusion.
A well-run grievance process protects both the employee and the business.
At Nexus Employment Consultancy, we support SMEs with grievances, disciplinary matters, workplace investigations and complex Employee Relations issues — from early risk assessment through to investigation strategy, documentation and outcome.
If a grievance has landed on your desk and you are unsure how to approach it, getting the structure right at the beginning is usually far easier than trying to repair the process later.
