(1) An employee's period of employment with an employer at a particular time is the period of continuous service the employee has completed with the employer at that time as an employee.
(2) However:
(a) a period of service as a casual employee does not count towards the employee's period of employment unless:
(i) the employment as a casual employee was as a regular casual employee; and
(ii) during the period of service as a casual employee, the employee had a reasonable expectation of continuing employment by the employer on a regular and systematic basis; and
(b) if:
(i) the employee is a transferring employee in relation to a transfer of business from an old employer to a new employer; and
(ii) the old employer and the new employer are not associated entities when the employee becomes employed by the new employer; and
(iii) the new employer informed the employee in writing before the new employment started that a period of service with the old employer would not be recognised;
the period of service with the old employer does not count towards the employee's period of employment with the new employer.
