If you have worked for your employer for at least one month, the statutory minimum notice you usually give when resigning is one week. Your employment contract may require a longer period, which normally applies instead, so check its notice and resignation terms. Employers generally must give at least one week’s notice after one month’s service, increasing by one week for each completed year up to 12 weeks, unless an exception applies. Pay in lieu of notice, garden leave and dismissal for serious misconduct can affect how notice works, so seek advice from ACAS or a solicitor regulated by the SRA if you are unsure.
