Underpaid - Accounts Receivable Specialist Interstate Batteries Employee Review

I'm severely underpaid for the amount of work they expect me to do. I am so underpaid that I rely desperately on my overtime just to make ends meet so holidays and pto cause me to not be able to pay my bills. I literally live down to the dollar every pay period and I spend all my time at work 10 hr days 5 days a week. I do the job of 2 people at other locations but bc I have experience and I am good at what I do they expect me to be able to do both jobs at the pay of just one person at 1 yr experience level.
