Tzitz Eliezer, Part 2:2

ציץ אליעזר

The laws pertaining to workers are dependent on the custom of the land, or even the custom of the city, which is set by the leaders who preside over all the communal issues in the city and who watch over its enactments, in partnership with the wise person who is appointed leader of the community (if there is someone such as this). These people are authorized to determine the conditions of work incumbent upon the employer and the workers, and, when determining these conditions, to establish fines and punishments for those who do not uphold these conditions. They also can grant the power of declaring a strike, as a means of pressure on the employer so that he will turn back from failing to uphold the conditions, if they find that this is the most effective tactic, for the power of the townspeople to make enactments, specifically when this is done in partnership with the city leader, is comparable to the power of the court to compel and to punish with all types of punishments and chastisements. Even more so is this the case, according to everyone, that they are able to establish punishments and to declare a strike over employment conditions that have already become the cusom of the land.
