Wage reporting when hours change weekly - 2 months and counting

My hours change every week at my new part-time job and I am afraid of reporting wrongly. There are 14 people counting on me, so I am trying to be careful. 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.
