So, I have been on supply in a school since day 1 of the term in September and have worked every day. On Tuesday afternoon, the school Business Manager informed me that I would not be required Wednesday to Friday. Expected pupil attendance and the number of events that were planned meant that I was not needed and that I should "start my Christmas break earlier" and that the school was having to manage their supply budget closely. This was delivered very clinically with no apology etc. It was followed up by an email confirming that I would not be employed on supply on the three days and confirming the days I would be paid for. I have not signed a contract (which suited me) although I had been told from the start that I was covering a one year career break. I had planned to stay at the school until the summer and then look at my options then. However, I have now agreed to cover a maternity leave in another school starting straight after the holidays. This post had been offered to me by a friend three weeks ago, I had said no as I had loyalty to the post I was covering. However, they were really struggling to get someone as I teach a shortage subject. This post also suits me for a number of reasons. On Thursday, I had a conversation with the HT at the new school, explained what had happened, showed him the email and he said I was free to sign a contract with him and I signed a contract until Summer! (he offered me a contract until next year but that does not suit me although he was delighted to get the post filled) I emailed the Business Manager back to thank her for confirming the days I would be paid for and informing her that I had signed a contract with another school and to pass on my thanks to the HT and that I would be in touch with the HoD on the Friday to confirm handover for my classes. I then had 4 missed calls in about 30minutes from the school. (I was in the gym so no phone) The HT sent an email saying that I had made a commitment to this post until the summer and that I was leaving my students without a teacher and that she was very disappointed (I do not teach any exam classes as when the timetable was made it was assumed they would not have a specialist teacher to cover this line of the timetable) I have emailed my HoD to confirm handover details- received no reply. Am I in the wrong?
