i just took a look at my paystub from last week and they didnt pay me for the three hours I came in early one day... will the extra hours be paid next paycheck or should I speak to somebody about this?
Definitely speak to somebody about it. Probably the store manager who has access to the time clock system. They'll probably have to manually put in your hours, and then your pay will come in for next week's check.
I've had this happen to me a couple times when I came in earlier than scheduled or when the time clock servers were down.
Tip, you can always check your current number of hours earned for the week at any time by doing an inquiry on the time clock when you punch in. That way, there are no surprises by having to wait for your check on thursday.
