I worked for a doctor for a short time who refused to pay her staff overtime. When I started, I found out that everyone in the office worked an average of 5 hours overtime per week. When I brought this to the doctor's attention, she shrugged it off and said she didn't have to pay overtime because she paid "salary" not "hourly". I checked with the department of labor and they assured me that even though she paid "salary", the office staff that were not "management" or in a "professional" or "exempt" position had the right to overtime. I told the staff this and they all indicated they had never demanded it, and were not interested in pursuing it, because they didn't want to lose their jobs. When I left the office, I filed for back overtime pay with the department of labor, but the office staff would not back me up in my claims during the investigation, so the labor department dropped my case. Moral of the story, unless you have others who are willing and able to corroborate your claims, or your office actually utilizes a time clock where your overtime is indisputable (the doctor's office did not), there's probably not a lot you can do. At least that was my experience. Do you have to keep a time log? Does your boss sign it weekly? If so, that would probably be just as good as a time clock. Good luck to you! I hope your experience in getting this issue resolved is much better than mine was!
