"S.1(1) A person discriminates against a woman in any circumstances relevant for the purposes of any provision of this Act if- (a)....... (b)he applies to her a requirement or condition which applies or would apply equally to a man but- (i)which is such that the proportion of women who can comply with it is considerably smaller than the proportion of men who can comply with it, and
"S.6(2) It is unlawful for a person, in the case of a woman employed by him at an establishment in Great Britain to discriminate against her- (a)...... (b)by dismissing her, or subjecting her to any other detriment."
"Staff on the career break scheme who work part-time will have continuous employment and there will be a short-term amendment of their contracted hours of work. Some benefits will be retained in full and other will be calculated on a pro rata basis according to the hours worked."
"10 The bonus undoubtedly was given to staff in order to persuade them to stay until the date of relocation but we are quite satisfied that it was not enhanced pay for that period. It was based on experience, age and service and we are satisfied that the number of women who could receive a bonus based on full-time service is such that the proportion who could comply with that would be very much smaller than men. So on that ground we are satisfied there has been discrimination.
"What has been put before us on behalf of the applicant is that by reason of the terms of the scheme....... which provided a bonus if an employee did not accept redeployment, that (sic) there has been discrimination because that was a condition which the majority of women would find more difficult to comply with than men."
"...... a practice could only be assumed to have an adverse disproportionate impact on part-time workers if it was a precondition for acquiring a particular benefit that a worker was in full-time employment"
"This particular pay practice lays down precisely identical rules for both full-time and part-time workers, and there is no condition which part-timers, unlike full-timers, are unable to meet."
