I am covering maternity and have just been given 4 weeks notice of the return of the postholder. My contract states I would be given 2 months before the end of term or 3 months before summer. I also signed a letter of appointment, the letter stated that my contract was temporary and the end date would depend on the decision to return of the postholder, but that I would be informed with notice of her decision to return. I have queried with the school about 4 weeks notice not matching my contract. They state that my appointment letter clearly states that I would be given notice of the postholder's decision to return and that is what they have done. I signed the appointment letter but no notice period is stipulated, the only notice period specified is on the contract. Should I go quietly in 4 weeks? Should I talk to the unions and fight this to leave at Easter when I should be served notice until this date? Do I have a leg to stand on or are they correct when they make reference to the signed appointment letter? Many thanks.
