Continuity of service is measured by reference to a ‘statutory week’ this is defined as continuous service and the amount of time that you have worked for an employer, or associated employer. Associated employers are outlined within the legislation.
Under the Employment Rights Act 1996, continuity of service is maintained if an employee moves to a new job with an ‘associated employer’ within a statutory week (Sunday to midnight on Saturday). In order to break continuity the break must exceed one statutory week. It is therefore possible to leave one employer on the Monday of week one and start work with a new employer on the Friday of week two and still maintain continuous service.
Continuous service is used to calculate redundancy payments and entitlement to other contractual benefits (i.e. sickness and maternity pay).
