Horrible waste of my time. - Customer Service Desk Supervisor Kmart Employee Review

There is a so-called "pay freeze" so I made the same minimum wage for 2 years of service. I was promoted to supervisor and was told it was a pay raise, but that never happened. I worked at the service desk where I was to be the cashier, do returns, answer phone calls, do western union, lotto, and many other things. Many times there would be no extra help and no other cashiers until later in the day. Doesn't corporate look at the turnover rate at this store? Its ridiculous.
