How do you report hours that vary week to week? after 16 years as an electrician's helper

I work some days through a staffing agency while still certifying. Pay posts on a different day from when I work. 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.

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