An employee who has both the right to return to work conferred by section 79 and another right to return to work after absence because of pregnancy or childbirth (under a contract of employment or otherwise) may not exercise the two rights separately but may, in returning to work, take advantage of whichever right is, in any particular respect, the more favourable.

Sections 79 and 81 to 84, and the provisions of the following Parts of this Act relating to the right conferred by section 79 (other than section 137(2)), apply, subject to any modifications necessary to give effect to any more favourable contractual terms, to the exercise of the composite right described in subsection (1) as they apply to the exercise of the right conferred by section 79.
