How do you report hours that vary week to week?, forklift operator here

I picked up part-time shifts as a forklift operator and I am confused about how to report them. I do not usually post, so bear with me. Sometimes my paycheck is late by a week. Who can I ask without risking my claim?

Thanks for writing this out. I went through something close to it 3 months ago, and it got easier once I kept a simple log of every call and form.
