Reporting part-time earnings while on benefits - first time posting

My hours change every week at my new part-time job and I am afraid of reporting wrongly. I have been trying to stay organised about it. Pay posts on a different day from when I work. Do you report when you earned it or when you were paid?

In my state the question was about the week I worked, not the week I was paid. Read the wording on your form carefully, or ask the claims line.
