Working at Frys Electronics two years ago, we opened on Thanksgiving and worked through till 10:00pm Friday night.
I got my punch detail the next week, and it showed everyone clocked out for a minute at midnight so no one go paid double time for working the crazy hours. They use some loophole about their transition from one day to the other. They split it up as if we'd worked two separate shifts, even though we never got a break.
When I saw what they did just to avoid paying double time, I was pissed! I can deal with crazy amounts of pissed off customers and crowds. I don't expect to be bent over while doing my job.
