Don't eat lunch. When you finally convince your boss to let you work 8 hour days with no break instead of 9 hour days with an awkward 1 hour unpaid break you can do nothing with, that's 1 hour you can spend on yourself that you didn't have before. Also, now you don't have to waste as much of your spare time exercising so the time savings are twofold.
Not everyone can do that unfortunately as it is illegal. We're "forced" to have a lunch break, which I support the idea of, I just hate that I have to stay the extra hour when "normal" full time jobs are 9-5 and the lunch is in that 8 hours...
That was one of the few the only advantage of living in Texas. It was not difficult to get out of that 1 unpaid hour "break" so I could go home earlier and get paid the same for spending less time at work. Lawmakers pushing for mandated unpaid breaks are helping corporations keep their employees at work longer.
Mandated breaks should be paid. Nothing personal gets accomplished in an hour, it is just a chance to recharge so you can work even harder. For that reason, it serves the company, and should be paid time.
