Reporting part-time earnings while on benefits - 6 months and counting

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

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

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