Distributive justice also pertains to various protections against harms or wrongs associated with work. Again, most societies place legal limitations on various conditions of work. These include protections against overwork via limitations on the length of the workday or workweek; bans on discrimination in hiring or promotion based on race, gender, religion, or other social categories; assurances that workplace risks and dangers are mitigated; and, at a wider societal level, prohibitions aimed at ensuring that individuals lives are not dominated by work at particular life stages (bans on child labor and provisions to make retirement possible). One important moral question about these protections is whether workers should have the right to bargain away some of these protections either for increased pay (as when employees negotiate higher wages in exchange for performing more dangerous jobs) or for enhancements in other protections.
