Paragraph 2

A person shall not be treated as satisfying the requirements of the preceding paragraph unless he had a right to (or, under a promise given to him by his employer, a reasonable expectation of) reinstatement in the employment last held by him before his war service, and, in the case of a person who ceases to be engaged in war service on or after the appointed day, he gives notice in writing to the Minister, within a period of two months after he ceases to be so engaged (or within such longer period as the Minister may for special reasons allow in a particular case), that he claims to be an employee on war service for the purpose of these Rules or of regulations made under Section 67 of the National Insurance Act.
