I am employed at a gym and train clients for an hourly rate determined by the gym in which they label on payroll as commission. I recently took on clients of a weight loss challenge in which they give us tickets when we train them that are dated and signed each time we train them. They get three training sessions a week and turn in a coupon signed each time. Then at the end of each week we turn them in so they can be sent to payroll. I am brand new at this job and thought the coupons were to be turned in according to our payroll. I was off by one day so a days worth of coupons were turned in the following week. Can my employer refuse to pay me for hours worked because my coupons were accidently turned in late? Is it legal under any circumstances not to get paid for hours worked? They are basically telling me too bad. The clients have already paid for their sessions, I trained them and now they don't want to pay me my commission. It is 12 hours of training......
