Reporting part-time earnings while on benefits - any advice?

I work some days through a staffing agency while still certifying. This is my first time dealing with any of this. Sometimes my paycheck is late by a week. Who can I ask without risking my claim?

I estimated and then checked my pay stub. When there was a small difference I wrote to the agency to correct it.

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