Susie Munro Editor's message: If your organisation is considering taking disciplinary action against an employee, it is essential that you carry out an adequate investigation, to establish the relevant facts before making a decision as to whether or not to proceed.

Even if you're sure you already know what happened, and it seems obvious that disciplinary action is required, a failure to carry out an investigation could lead to you having to compensate the employee for a procedurally unfair dismissal.

You should follow the principles of the Acas code of practice on disciplinary and grievance procedures when deciding on the extent of the investigation and who should carry it out. Your investigation is likely to include interviews with the employee concerned and any witnesses to the alleged misconduct, as well as consideration of any relevant documents.
