It can be worthwhile, but this depends on the strength of your evidence, the impact on you and the remedy you are seeking. Keep relevant documents, raise the issue through your employer’s grievance procedure where appropriate, and contact Acas for free guidance. Most employment tribunal claims require you to notify Acas first, and strict time limits often apply, commonly three months less one day from the incident. A solicitor regulated by the SRA or a trade union may help you assess your options and potential costs.
