Reporting part-time earnings while on benefits, production planner here

My hours change every week at my new part-time job and I am afraid of reporting wrongly. Any experience at all would help. Pay posts on a different day from when I work. Who can I ask without risking my claim?

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

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
