Reporting part-time earnings while on benefits after 12 years as a paralegal

I picked up part-time shifts as a paralegal and I am confused about how to report them. Pay posts on a different day from when I work.

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

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