Wage reporting when hours change weekly, customer-service rep here

I picked up part-time shifts as a customer-service rep and I am confused about how to report them. I have read a lot of threads here and could not find my exact situation. Sometimes my paycheck is late by a week. 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.
