If you believe employees can use Apple for the work they did while off the clock, why can't Apple countersue the employees for the work they didn't do while on the clock....all the bathroom breaks, all the coffee breaks, all the web surfing, all the chatting, etc?
That's really not the way US Labor Law for hourly-wage employees works... for instance, just today, there was a study published about the frequency with which individuals earning at or near minimum wage are paid less than they are legally owed...

Low-wage workers are routinely denied proper overtime pay and are often paid less than the minimum wage, according to a new study based on a survey of workers in New York, Los Angeles and Chicago.
The study, the most comprehensive examination of wage-law violations in a decade, also found that 68 percent of the workers interviewed had experienced at least one pay-related violation in the previous work week.
The study was conducted multi-site by major universities, and while I haven't seen the whole report yet, it looks reasonably credible.
It's common -- it's certainly not a case of Apple being an evil standout, but it doesn't seem like a case where there is absolutely no prima facie claim, either. For salaried workers (like myself), I do generally buy the pinch here, pinch there type of argument, but these individuals earn a lot less money than we do.
