"6. It is obvious from the documents before me that the governors based that notice upon a contract which had been issued to a number of other teachers over the years, though not to these Applicants. It was on a standard form for teachers in Independent schools called The Joint Four, those four being the four teaching unions in Independent schools. It was clear to me that this contract was of wide, if not universal application. Clause 8 of that agreement reads as follows:
"16. This is a case where I have to imply a clause which did not exist. Clearly both parties contemplated that had they applied their minds to it they would have agreed a clause which covered the ending of employment. The question for me is what was that clause.
"A contract (standard AMMA apart from the length of notice which at St Michael's is one full term on either side) will be offered to you."
"A contract is offered at the end of the first term. This is standard AMMA with the change to the period of notice which is one full term either side. ..."
"11. Whatever each individual contract said, and it was the Applicants' submission that in effect they all had the same contract, and I accepted this. ..."
"17. Quite clearly the joint four contract was one which was very common in the profession, and of the choices I have it seems to me that it was that agreement which the parties would have adopted at the outset of employment if they had applied their minds to it. It was an agreement which was clearly common in the profession, it allowed a teacher to resign in the first week of the term as well as an employer to end the contract, it provided in this case for some 17 weeks notice, and whilst in the event, a number of these teachers could not get jobs in the September I cannot say it was oppressive and unreasonable and that the Applicants would undoubtedly have rejected this. It is for the Applicants to prove their case on the balance of probabilities and they have not convinced me that they have discharged that burden in this case."
