Wage reporting when hours change weekly - 6 months and counting

My hours change every week at my new part-time job and I am afraid of reporting wrongly. Any experience at all would help. The form asks for gross earnings, which I do not see until later. Who can I ask without risking my claim?

Thanks for writing this out. I went through something close to it 6 months ago, and it settled down once I kept a simple log of every call and form.

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.
