Who do some schools expect too much from supply teachers ? At the start of term I agreed to cover in a school for a teacher who was expected to be off for at least 2 weeks. I told the agency I would be happy to do it as long it wasn't for much longer as I don't like doing longterm work cos of all the extra stress etc. I did the first 2 weeks and the school told me the teacher would probably be off until half-term so I told the supply coordinator that I would be happy to do another 2 weeks. I was planning the lessons, setting homework, marking books in my free lessons, which is more than I would normally be expected to do. Just before 3 weeks was up I mentioned to the head of maths that I was finishing next week and she didn't take it well. On Friday she told me that I wasn't needed for the final week as she had asked a retired teacher to come instead. I didn't bother arguing (what's the point) but I was upset because I had given them plenty of notice whereas she had told me on Friday afternoon so I had to try and get other work for the following week. Next time I'll just ring the agency when I've had enough. I've worked in another school on Monday and Tuesday and having a day off today. Why should a supply teacher have to do the same as a permanent teacher when I don't get paid to scale, or get pension or sick pay?
