Wage reporting when hours change weekly after 7 years as a welding apprentice

My hours change every week at my new part-time job and I am afraid of reporting wrongly. I worked as a welding apprentice before this. Sometimes my paycheck is late by a week. 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.
