How do you report hours that vary week to week? - first time posting

My hours change every week at my new part-time job and I am afraid of reporting wrongly. I am in Cleveland, in case local advice matters. Sometimes my paycheck is late by a week. Who can I ask without risking my claim?

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

I estimated and then checked my pay stub. When there was a small difference I wrote to the agency to correct it.
