Last week I was delighted to accept a long term supply post in a shortage subject. This was to cover the rest of the year to cover maternity. It was understood I would be expected to become a "full time" member of the team and do parents evenings, marking . assessment etc. The first 12 weeks was to be at rate x and then the rest of the contract would be x+£40 per day. Just had a phone call from agency saying whole contract would be just x per day. The reason given was the head cant afford the extra and said she could get supply at a cheaper rate. I am a very experienced teacher and it is a very tough school to work at. My question is don't the school have to pay a standard rate after 12 weeks and can I accept the lower rate and just plan and deliver lessons. It seems the school is trying to get me on the cheap, I have financial problems at the moment so do I have a leg to stand on? Can agencies just pay what they can get away with.
