Waiver is a unilateral declaration of will or a conduct implying an intent, by which the employee waives the exercise of a right. A settlement is a contract by which the parties, by making mutual concessions, end a dispute that has already begun or prevent a dispute from arising between them.

The worker may freely waive or settle only for rights that can be decided by law, National Collective Labour Agreement or individual contract, which are better than those laid down by law or NCLA (i.e., extra allowance, additional monthly payments, and additional leave not provided for by the National Collective Labour Agreement) . a waiver or settlement for rights that cannot be waived and that have already been made available to the worker, is only possible if it is made in one of the “protected proceedings.”

A waiver or settlement of future rights, i.e. rights that have not yet become available to the worker, is always null and void.
