How do you report hours that vary week to week? after 16 years as an HR coordinator

I work some days through a staffing agency while still certifying. The form asks for gross earnings, which I do not see until later. Did anyone get an overpayment notice from a mistake?

The claimant handbook has worked examples for part-time pay. Mine was clearer than the phone line.

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