Reporting part-time earnings while on benefits after 6 years as an HR coordinator

My hours change every week at my new part-time job and I am afraid of reporting wrongly. Sometimes my paycheck is late by a week. Did anyone get an overpayment notice from a mistake?

Keep everything in writing and save the confirmation numbers. It saved me later.

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