Reporting part-time earnings while on benefits after 8 years as an accounts payable clerk

I work some days through a staffing agency while still certifying. There are 8 people counting on me, so I am trying to be careful. 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 10 months ago, and it settled down once I kept a simple log of every call and form.
