A right to a guarantee payment does not affect any right of an employee in relation to remuneration under his contract of employment ("contractual remuneration").
Any contractual remuneration paid to an employee in respect of a workless day goes towards discharging any liability of the employer to pay a guarantee payment in respect of that day; and, conversely, any guarantee payment paid in respect of a day goes towards discharging any liability of the employer to pay contractual remuneration in respect of that day.
For the purposes of subsection (2), contractual remuneration shall be treated as paid in respect of a workless day—
where it is expressed to be calculated or payable by reference to that day or any part of that day, to the extent that it is so expressed, and
in any other case, to the extent that it represents guaranteed remuneration, rather than remuneration for work actually done, and is referable to that day when apportioned rateably between that day and any other workless period falling within the period in respect of which the remuneration is paid.
