Gross misconduct and appeal procedure under labour rules define workplace offences and set time-bound appellate review. Gross misconduct includes wilful destruction of employer's property, workplace assault, moral turpitude convictions, theft or fraud connected with employer's business, and wilful breach of safety measures. Appeals under section 68(2) are to be filed in Form-XII before the competent authority, which must notify the employer, seek a reply and documents, and decide the appeal, ordinarily within three months, with a further recorded extension of up to three months. Failure by the employer to respond may lead to an ex parte decision.
