How do you report hours that vary week to week? - 26 weeks in

I work some days through a staffing agency while still certifying. There are 12 people counting on me, so I am trying to be careful. The form asks for gross earnings, which I do not see until later. Do you report when you earned it or when you were paid?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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