Sometimes management will skim off the top of your hours to get you under 40 hours, preventing you from receiving overtime even if you've worked them. Unless you approach management about taking your hours away, you will not be compensated for your time. Management varies from store to store, but management at my store chased women around like they were pieces of meat even when they were aware the female employees were not single and that it could cost them their jobs. Management tends to play favorites and will let certain employees get away with not performing their job duties while working capable employees like dogs. If they know that you can perform the duties of 2 employees and can get away with paying you for doing the work of 1, they'll utilize that to their advantage and trim hours around the store, forcing the remaining staff to do double the work. I've handed in my resume to be submitted for consideration for management positions multiple times, but am in the firm belief that management hasn't sent my resume into the corporate office out of fear of losing me as an asset to their particular store.
