It is my understanding that if one works over 40 hours per week, he is entitled to time and a half pay for all hours over 40. This is federal law. I have had quite a few paychecks from my job where overtime was not paid to me. I have the pay slips to prove this. I regularly work sundays and holidays (fourth of july, labor day, memorial day, etc.) Are there any exceptions to the overtime law? Is there a valid reason why I was never paid overtime?
