I remember having to pay the stupid union dues for my little part time job at Kroger back in 1990...seemed like it took half my paycheck.
They have incentives for their employees that my relative tries to do.
I can’t remember what they are called but if you go to the customer service desk and praise one of the workers for going above and beyond they get some kind of coupon to use..like $2 or $3 dollars. If you go online to praise them they get a free lunch coupon or something similar. Things like that.
