Reporting part-time earnings while on benefits after 16 years as an accounts payable clerk

My hours change every week at my new part-time job and I am afraid of reporting wrongly. This is my first time dealing with any of this. Pay posts on a different day from when I work. Did anyone get an overpayment notice from a mistake?

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