In recruiter context

Definitions vary by employer but common examples: theft of company property, deliberate falsification of records, violence or harassment, breach of confidentiality, drug or alcohol use at work, deliberate sabotage. Even gross misconduct dismissals must follow a fair process — typically a disciplinary hearing, appeal right, and clear documentation. Wrongful gross-misconduct framing is a common employer mistake that gives rise to unfair dismissal claims; employees terminated for gross misconduct should challenge the framing if it's not justified.
