Resignation in labor law

around the new n. 3 of art. 337 of the portuguese labor code

Abstract

The study sets out to answer the following problem: can the rights granted to the worker by mandatory law be validly waived
by their holder? Doesn’t the imperative nature of the labor standard imply, as a natural consequence, even if implicit, the non-renouncea bility of the right it grants to the worker? These are relevant questions for the labor standard, especially from the perspective of reflecting on whether the imperativeness or inderogability of the standard does not imply the unwaivability of the corresponding right.
