"An equality clause is a provision which relates to terms (whether concerned with pay or not) of a contract under which a woman is employed (the `woman's) contract'), and has the effect that - (a) where the woman is employed on like work with a man in the same employment -"
"A woman is to be regarded as employed on like work with men if, but only if her work and theirs is of the same or a broadly similar nature, and the differences (if any) between the things she does and the things they do are not of practical importance in relation to terms and conditions of employment; and accordingly in comparing her work with theirs regard shall be had to the frequency or otherwise with which any such differences occur in practice as well as to the nature and extent of the differences."
"The other comparator is Mr Draper who was head of the Business Department at Mr Sheppard's school at Adwick. Again Mr Sheppard was of considerable assistance in relation to Mr Draper."
"There is no `A' level at the present time and Mr Draper has never done `A' level and could not do it without further training and indeed if they did `A' level Business Studies it would be in another department. Mr Draper has some part time staff and one unqualified teacher and Mr Sheppard says an unqualified teacher needs more supervision. He said that Mr Draper had a number of other duties and he gets the higher `D' allowance. It appears he has responsibilities as a housemaster and for vocational work. In relation to those other things outside his business study work Mr Sheppard said this:
"Understanding the forcefulness of those submissions the tribunal does nonetheless have as the starting point the evidence of Mr Sheppard. On the basis of his evidence we have no difficulty at all in identifying the business studies element of Mr Draper's work as being within a grade `B' allowance. That seems to us to have clearly been the judgement of his headmaster and was the starting point which gave him the leap to grade `D' for the other matters and without which it is difficult to see how he would have arrived at grade `D'. If the evidence had been that Mr Sheppard had taken an overall view and the whole thing was lumped together at grade `D' and you could not disentangle it then of course Mr Scowcroft's submissions would have had a great deal of force. But that was not the evidence and it is the evidence upon which we must base our decision."
"At the end of the day, therefore, we are satisfied that in applying section 1 (4), whereas it is usually right to disregard the time at which the work is done, it is not permissible in ordinary circumstances to disregard any part of the work actually done in practice. We say `in ordinary circumstances,' for it is possible to believe that there will be unusual cases where it might be right to proceed otherwise. Those cases will have to be dealt with when they arise; but what we have in mind is the kind of example cited in the argument where upon analysis it can be seen that part of the work, although subsumed under the general description of the tasks of the employee, is in effect a separate and distinct job. For example, when comparing two cleaners, one male and one female, both of whom do identical work during the week, it might be right to ignore work of a quite different kind done by the man coming in, say on Saturdays, in order to cut the grass. Each such case must depend on precise facts."
