No, because that encourages employees to short change customers in order to line their pockets. Just like employers don’t (can’t, I assume) require the cashier to correct short drawer with their own money.
Remember, as stated in the OP, these are not tipped employees (well, they are, but they’re getting paid a regular wage, not a waitstaff wage).
Bill Door, I run a store, I’m aware that it would be illegal to do this to a tipped employee, but what about a regular one?
Doug, yes, it’s very illegal to fire someone for reporting you, that’s pounded in to my head all the time. The OP is totally welcome to report the employer, but here’s how I see that playing out.
The OP reports the employer, employer fires OP, OP out of a job. Illegal, yes, but the OP is out of a job regardless.
Or
The OP reports the employer, employer takes his lumps and moves on with life. A few days weeks later, money is missing from the register, employer figures out who made the mistake (or stole the money) and fires that person. OP (for the sake of the argument) is out of a job.
You could report him and see what happens. Honestly, might be nothing, he might never do it again and that’ll be the end of it, he might not have known that it was illegal, it may just have been the way he made the register work out. Contrary to what everyone seems to think, not every.single.employer is out to screw their employees at every opportunity.
You’re other option is look for another job. If you’re working for minimum wage (plus tips) at a DD, a lateral move to another fast food place shouldn’t, I assume, be a difficult transition, financially or otherwise.
