If you toil in a factory, and your employer wants you to put in twelve-hour days, this demand will be clearly specified in a labor contract, in black and white, in a form that can be pointed to and argued about. Your union can fight back.
Mate, what kinds of jobs do you think most of the working class has these days? Hint: it's not manufacturing. Most employees are in the retail/service sectors or part of the gig economy. There are no unions to be found.
