Part-time employees
55.—(1) If a person in a part-time employment elects under regulation 54, the periods mentioned in that regulation must be reduced in the proportion that his contractual hours bear to the number of contractual hours of a single comparable whole-time employment.
(2) But the amounts of his additional contributions must be calculated as a percentage of his actual pay (subject to regulation 54(7) and (8)).
(3) Where any person has made such an election, if–
(a)his employment ceases to be part-time and becomes whole-time employment;
(b)his employment ceases to be whole-time and becomes part-time employment; or
(c)his contractual hours in the part-time employment alter,
his additional contributions continue to be payable at the same percentage of his pay, but the additional period counted by reason of contributions paid after the change must be calculated as if the change had occurred immediately before the election.
(4) Paragraphs (1) to (3) do not apply to old elections.
(5) However, the member may elect for paragraph (2) to apply to an old election and, if he does so, the additional period counted by reason of contributions paid after that election must be calculated as if paragraphs (1) to (3) had always applied as respects his old election.
(6) A member’s election under paragraph (5) must be made by giving notice in writing to the appropriate administering authority not later than one year before his NRD.
(7) Old elections are elections made before 21st December 1987.
