see also ‘Misconduct’ - Gross misconduct is misconduct so serious that the employer is entitled to dismiss for a first offence. Generally it constitutes behaviour which could threaten the business itself and its reputation or could threaten other employees, customers etc. As an employer, it is vital to have written definitions of what constitutes gross misconduct and to communicate such guidelines, whilst making clear that other behaviours not outlined in the definitions may constitute gross misconduct. Also the consequences of committing such activities should be made clear and employees should be made aware that they are not entitled to their notice period.
