Employment Rights Act 1996

39 Reduction of pay etc

(1) This section applies where—

(a) under the contract of employment under which a shop worker or betting worker who satisfies section 36(2)(a) was employed on the day before the relevant commencement date, the shop worker or betting worker was, or might have been, required to work on Sunday before the relevant commencement date,

(b) the shop worker has done shop work, or the betting worker has done betting work, on Sunday in that employment (whether or not before that date) but has, on or after that date, ceased to do so, and

(c) it is not apparent from the contract what part of the remuneration payable, or of any other benefit accruing, to the shop worker or betting worker was intended to be attributable to shop work, or betting work, on Sunday.

(2) So long as the shop worker remains a protected shop worker, or the betting worker remains a protected betting worker, the contract shall be regarded as enabling the employer to reduce the amount of remuneration paid, or the extent of the other benefit provided, to the shop worker or betting worker in respect of any period by the relevant proportion.

(3) In subsection (2) “the relevant proportion” means the proportion which the hours of shop work, or betting work, which (apart from this Part) the shop worker, or betting worker, could have been required to do on Sunday in the period (“the contractual Sunday hours”) bears to the aggregate of those hours and the hours of work actually done by the shop worker, or betting worker, in the period.

(4) Where, under the contract of employment, the hours of work actually done on weekdays in any period would be taken into account in determining the contractual Sunday hours, they shall be taken into account in determining the contractual Sunday hours for the purposes of subsection (3).

(5) For the purposes of section 36(2)(b), the appropriate date in relation to this section is the end of the period in respect of which the remuneration is paid or the benefit accrues.
