Wage reporting when hours change weekly

I picked up part-time shifts as a paralegal and I am confused about how to report them. I worked as a paralegal before this. Pay posts on a different day from when I work. Did anyone get an overpayment notice from a mistake?

The claimant handbook has worked examples for part-time pay. Mine was clearer than the phone line.

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