Reporting part-time earnings while on benefits after 12 years as a software tester

My hours change every week at my new part-time job and I am afraid of reporting wrongly. There are 12 people counting on me, so I am trying to be careful. Sometimes my paycheck is late by a week.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
