13.—(1) Subject to subsection (2), an employee shall not be entitled to a redundancy payment in pursuance of a notice of intention to claim if, on the date of service of that notice, it was reasonably to be expected that the employee (if he continued to be employed by the same employer) would, not later than four weeks after that date, enter upon a period of employment of not less than thirteen weeks during which he would not be laid off or kept on short-time for any week.

(2) Subsection (1) shall not apply unless, within seven days after the service of the notice of intention to claim, the employer gives to the employee notice (in this Part referred to as a counter-notice) in writing that he will contest any liability to pay to him a redundancy payment in pursuance of the notice of intention to claim.

(3) If, in a case where an employee gives notice of intention to claim and the employer gives a counter-notice, the employee continues or has continued, during the next four weeks after the date of service of the notice of intention to claim, to be employed by the same employer, and he is or has been laid off or kept on short-time for each of those weeks, it shall be conclusively presumed that the condition specified in subsection (1) was not fulfilled.

(4) For the purposes of F33[section 12] and for the purposes of subsection (3)—

(a) it is immaterial whether a series of weeks (whether it is four weeks, or four or more weeks, or six or more weeks) consists wholly of weeks for which the employee is laid off or wholly of weeks for which he is kept on short-time or partly of the one and partly of the other;

(b) no account shall be taken of any week for which an employee is laid off or kept on short-time where the lay-off or short-time is wholly or mainly attributable to a strike or a lock-out, whether the strike or lock-out is in the trade or industry in which the employee is employed or not and whether it is in the State or elsewhere.
