Reporting part-time earnings while on benefits

My hours change every week at my new part-time job and I am afraid of reporting wrongly. It has been weighing on me all week. Pay posts on a different day from when I work. Do you report when you earned it or when you were paid?

Report honestly and keep your stubs. An honest small error is much easier to fix than a missing report.

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