Mental day

H added out to do a days supply today. When I was booked I was told I would be paid on 'Cover supervisor' rate, which is about half the full teacher rate. I agreed because I need the money and was told work would be set and all I had to do was supervise.
The work was set and was clear enough BUT out of 5 lessons 3 were bottom sets!!! And believe me you cannot just 'supervise' bottom sets. I basically taught all day - for £50 rather than £110!
This evening it's booze and chocolate to rid myself of the memory :-)
