If you have worked for your employer for at least one month, the statutory minimum notice you must usually give when resigning is one week, unless your contract requires longer. When an employer dismisses you, statutory notice is generally at least one week after one month’s service, rising to one week for each completed year after two years, up to 12 weeks. Your contract may provide a longer notice period, and different rules can apply to gross misconduct, redundancy or fixed-term work. Check your contract and the relevant gov.uk guidance; an employment solicitor can advise on your circumstances.
