How do you report hours that vary week to week? - what worked for you?

I work some days through a staffing agency while still certifying. I am in Charlotte, in case local advice matters. The form asks for gross earnings, which I do not see until later. 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.

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