87.1. No agreement or decree may, with respect to a matter covered by a labour standard that is prescribed by Divisions I to V.1, VI and VII of this chapter and is applicable to an employee, operate to apply to the employee, solely on the basis of the employee’s hiring date, a condition of employment less advantageous than that which is applicable to other employees performing the same tasks in the same establishment.
The same applies in respect of a matter corresponding to any of the matters referred to in the first paragraph where a labour standard pertaining to that matter has been fixed by regulation.
Any distinction made solely on the basis of a hiring date, in relation to pension plans or other employee benefits, that affects employees performing the same tasks in the same establishment is also prohibited.
