Workplace harassment linked to a protected characteristic—such as sex, race, disability or religion—may fall under the Equality Act 2010, while other bullying could involve different legal issues. Keep records of incidents, witnesses and any messages, and consider using your employer’s grievance procedure unless that would be unsafe or inappropriate. Most tribunal claims have a short time limit, usually three months less one day from the incident or last incident; you will normally need to notify ACAS for Early Conciliation first, which can affect the deadline. Consider speaking promptly to an employment solicitor regulated by the SRA or contacting ACAS for guidance.
