DD (23) works part time as a waitress at a posh restaurant whilst she's studying. She seems to be very good at the job and often gets £50+ in tips per shift, but is made to put it in the tips jar at work. Once a month or so, everyone gets a cut of the tips, including management, on a pro rata basis for hours too, and DD is lucky if she ends up with £10 in tips per month, which seems a bit unfair.
Can her work do this?
