What notice period should be given in a contract?

Notice clauses should provide for a minimum period of notice at least equivalent to the statutory minimum period of notice. If there is no express clause in the contract, the employee is entitled to a reasonable period of notice at common law (which cannot be less than the statutory entitlement). If an employee's contract is terminated after one month but before two years' service has been completed, statutory notice is one week. After two years and up to 12 years' service, the statutory notice period is one week for each completed year of continuous service. For employees with more than 12 years' service, the minimum notice period is 12 weeks.
