You may be in for a shock then. I had a lengthy discussion with my employer after reading on here and another site I frequent about the end of the 40 hour work week. Turns out that Denny's and Papa John's aren't the only one's considering the actions they have planned, they are the tip of the iceburg. My employer (not named at his request) is headed the same direction and believes the 40 hour week will die nationwide by the end of 2013. Employers can't afford to give people health benefits anymore because of Obamacare. He flat out told me they won't have ANY full time employees by the end of the year, before Obamacare is fully implemented, and his feeling is the only employers that will be able to afford full time employees will be the one's that got a free ride and a kiss from the President (certain Unions, McDonald's, etc)
So... call me a liar, try to prove me wrong, talk to your boss... I expect to lose 10 hours a week by June 1st, and overtime will no longer exist. That sucks.
