How do you report hours that vary week to week? after 15 years as an electrician's helper

I work some days through a staffing agency while still certifying. Sometimes my paycheck is late by a week. Who can I ask without risking my claim?

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.
