I work two days a week ( I have a second job) and I was only payed for one day. I know for I clocked in and out for both days. Do I have to talk to my csm?
Yes, ask your CSM. They normally do payroll corrections at my store.
Whoever does payroll can audit your punches. It will show if you punched or not.
Unfortunately, after you are able to show that you were there, you won't get paid for it until the next paycheck.
