Was brought into a teaching post by recruit agency at a MAT to start absolutely ASAP as the full time teacher who was offered the post through the system HR etc and was due to start, realised it was too much and quit. They had 3 days to offer Per week but head stated more hours/days for me could be found including cover and was happy to recruit as full time post if that was what was required. I said I couldn't do .5 of a post. The head said not to worry he could sanction it but I needed to start next day 9:00am but also stated that to begin immediately it'd have to be through umbrella Co. as I would need to complete the MAT's lengthy application procedure etc.to get the FT job. I kind of got the feeling the Head was just agreeing to anything to get me into the class to teach a course specialism of mine across 4 year groups which is less common. However i was pushed by the head to agree a salary there and then and negotiated one. The head shook my hand on a figure I proposed it was felt was reasonable, and my agency were informed; I would be hired full time for a finders fee which is usual. The secretary then preceded to fuddle around for good few days failing to send the application and other details. Meanwhile there I was totally in the deep end of a subject left somewhat in array understanding the curriculum and taking on some pretty difficult (unruly) classes straight away. Finally I get the application process complete and request viewing the contract offer ASAP. After a few days sure enough as I figured, I get called in to the head's office - The head states : unfortunately the MAT board had rejected his appointment and that as he was short some hours with other teachers as some courses did not run. The courses I was running, as well as being form tutor would have to be taken up by any spare hours any other teachers had on a rotor basis and thanked me for my picking up the ball at short notice but unfortunately my services would longer be needed. I knew they just wanted to buy time to get the classes set-up and organised from term start and till they could look at things. I can't help thinking that the head told me they had the weight to sanction this position and a greed a contract there and then and shook my hand to seal the deal. They know though that unless I have paperwork to back it all up i'm stuck, so I left politely and thanked them. I was used!
