If one of your employees raises a grievance at work, against one of their colleagues, you need to carry out an investigation into the situation, before you make any decisions. How do you go about doing this?
The first thing to consider is that the person against whom the grievance has been raised cannot carry out the investigation. Look for an impartial party to do it, who should decide what information they need in order to fully understand the situation. They should then interview the person who has raised the grievance, before speaking to the other party and anyone else involved. They should produce written evidence and be prepared to look for evidence both supporting the employee and against them.
All people involved should be asked not to discuss the allegation, or look for corroborating evidence or verification of what the employee and other staff are saying. They should also keep an open mind, as what they uncover may not be what anyone expects. For example, someone may be unhappy at work because of a family bereavement they haven’t told anyone about.
The next stage is to respond to the person who raised the grievance, with your decision based on the evidence. It may be appropriate to bring the two people together to discuss the evidence so that they can discuss the situation and plan how to resolve the situation. You must always respond to a formal grievance in writing, with your decision based on your investigation and offer the right of appeal.
The point of carrying out an investigation is so that you do not blunder into a grievance situation, without first finding out what is really going on. If you don’t have your own policy to follow, then use the guidelines published by Acas. As with most employment matters, following a clear process will keep you safe, if an aggrieved member of staff doesn’t like the way in which their grievance has been handled!
