(a)the contract under which he is employed by the employer is terminated by the employer (whether with or without notice),
(b)he is employed under a contract for a fixed term and that term expires without being renewed under the same contract, or
(c)the employee terminates the contract under which he is employed (with or without notice) in circumstances in which he is entitled to terminate it without notice by reason of the employer’s conduct.
(2) Paragraph (1)(c) does not apply if the employee terminates the contract without notice in circumstances in which he is entitled to do so by reason of a lock-out by the employer.

(4) In this Part the “obligatory period of notice”, in relation to notice given by an employer to terminate an employee’s contract of employment, means—
(a)the actual period of the notice in a case where the period beginning at the time when the notice is given and ending at the time when it expires is equal to the minimum period which (by virtue of any statutory provision or otherwise) is required to be given by the employer to terminate the contract of employment, and
(b)the period which—
(i)is equal to the minimum period referred to in sub-paragraph (a), and
(ii)ends at the time when the notice expires,
in any other case.
