How do you report hours that vary week to week? (Boston)

I picked up part-time shifts as an IT help-desk technician and I am confused about how to report them. Pay posts on a different day from when I work. Did anyone get an overpayment notice from a mistake?

Report honestly and keep your stubs. An honest small error is much easier to fix than a missing report.

Keep everything in writing and save the confirmation numbers. It saved me later.
