How do you report hours that vary week to week? - 13 months and counting

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

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.
