So will they be forced to pay backpay to all the employees Apple stole from up to this point? It's unclear if retroactively enforced means backpay, but it should.
Would it be pay at the hourly contracted rate, or pay to meet minimum wage when the extra hours are considered?
What should happen is a penalty for the CEO. I'd like to see Cook spend a few weeks in jail, incommunicado because I'm sure this was done at his direction. The government will never do anything to hurt such a company's bottom line in a significant way, however. If a regular person steals fifty cents worth of merchandise from the Apple store all hell will rain down upon him, but if Cook steals millions from his employees, he's a great CEO.
