Wage reporting when hours change weekly - what worked for you?

I picked up part-time shifts as a security officer and I am confused about how to report them. Pay posts on a different day from when I work. Who can I ask without risking my claim?

Thanks for writing this out. I went through something close to it 14 months ago, and it got easier once I kept a simple log of every call and form.

Report honestly and keep your stubs. An honest small error is much easier to fix than a missing report.
