Wage reporting when hours change weekly (Kansas City)

My hours change every week at my new part-time job and I am afraid of reporting wrongly. Sometimes my paycheck is late by a week. Do you report when you earned it or when you were paid?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
