Republicans want to do away with overtime and the 8 hour day.

The House will be voting on H.R. 1406, The Working Families Flexibility Act, which lets employers offer "comp time" instead of overtime pay. The problem is that employers will pressure workers to take comp time instead of overtime, which reduces paychecks and gets rid of the incentive to hire more people. Later, the employees will be pressured to not take that comp time, or will have to be "on call," etcetera.
It is important to note that the law does not guarantee workers the right to actually use the comp time they get instead of extra pay. Employers can put it off forever. You can't use this time when you want to, only when the employer decides it is okay.
