Hey, my paycheck is short $39.95! What'd you do with my money!?
My usual answer to this....the government let the Bush tax cuts lapse, so your taxes have gone up. I have to bite my tongue NOT to mention obummer did it!!
We have many, many more folks whose checks are seldom the same, than salary or normal 40 hour weekers.
The question most often heard is, "You didn't pay me the right hours. You shorted me". And my answer is we pay you the hours turned in by whoever does your payroll, probably your supervisor. You need to talk to them about hours turned in. Of course, they never hear the reason, just repeat "you paid me wrong". BUT...I persevere, and repeat as many times as necesary that I cannot help them. They must talk to their supervisor, agree on hours owed, and then the supervisor will let me know any additional hours needed. And, no, I will not call the supervisor...you need to work it out between you. I hear back from maybe a quarter about more hours due.
