"12 We have listened carefully to the evidence and read all the documents before us and regretfully come to the conclusion in this case - regretfully because we respect the applicant as a person of supreme integrity and honesty - that the applicant has failed to make out her case. Though, undoubtedly, she had formed the opinion after the discussion on 3 September that she was to be offered work at home on some basis or other and though she drew the conclusion that the basis of employment would be a pro rata hourly rate and that it would probably amount to two days a week because that is what happened to another accounts clerk when she had returned from pregnancy, there is nothing at all in the evidence to show that the discussions conducted with the respondent arrived at that point of agreement or anywhere near, and, indeed they were merely discussions in our view about what could happen - it was a possible scenario. That means that there was on 3 September no variation of the contract of employment. In order for there to be a variation of a contract there must be a meeting of minds. Each side must be clear in its own mind of the common result of the discussion - that is to say a change in the terms and conditions. In this case there was no arrival at a common view of what the new arrangement was to be; it therefore was merely a discussion about discussions, a discussion about possibilities for the future and no more."
