"(1) In relation to sex discrimination- (a) section 6(1) ... (c) does not apply to any employment where being a woman is a genuine occupational qualification for the job, and
"(b) The tribunal is of the view that the circumstances in the present case fall within the provisions of section 7(4) of the 1978 [ sic ] Act. The tribunal did not accept Mr Forrest's evidence in its entirety. If the major part of the time of the salesperson was to be spent in duties other than sales, the tribunal is at a loss to understand why the advertisement concentrated solely on sales techniques and mentioned nothing about any of the other matters. Mr Forrest told the tribunal that those other matters were mentioned at interviews with candidates for the post but the tribunal found it odd that, if there were such duties which occupied, according to Mr Forrest, 33 hours per week as compared with 7 hours per week spent on selling, such other duties were not mentioned in the advertisement. We were, therefore, suspicious as to the accuracy of the percentage of time which Mr Forrest ascribed to the working practices other than sales. The tribunal is satisfied, based on the evidence of Mr Forrest as to what the duties in the changing room, saunas, sunbed room and toilet, that those duties occupied a comparatively small amount of time. The tribunal accepts it would not be proper for a man to be entering the changing room sauna area, sunbed room and toilet. However, in the view of the tribunal, there is nothing wrong with a man attending the machine room, as the women occupying that room would be dressed and physical contact would be small, if at all, and such physical contact that there would be would be quite normal in training facilities. The tribunal can see nothing untoward in a man attending the dance floor when aerobic sessions were in progress. (c) Section 4 refers to "undue convenience". Whilst the tribunal is of the view that the employment of a man might cause some inconvenience to the respondents it would not amount to "undue inconvenience", as there would, at the time a man was present on the premises, be three to four women employees which number of [ sic ] sufficient to meet the respondents' likely requirements in respect of the duties above referred to."
