My new job (below minimum wage and fast food) has been sending me home hours before my shift ends because we’ve been slow or because “labor is expensive”. Normally I wouldn’t mind this as I hate fast food jobs, but I really need the money/hours. I’m new like I said so I’m not even fully trained, I just feel there should be SOMETHING I can do, be it cleaning, learning or just helping. Is there anything I can say next time to maybe curb this problem?
