Employment – Equality of treatment of men and women. The employment tribunal, in considering the employee's claim for equal pay, found that the employee's work had been of equal value to that done by a male comparator and that the employer had failed to make out the genuine material factor (GMF) defence. The Employment Appeal Tribunal, in dismissing the employer's appeal, held, inter alia, that the tribunal's findings had not been shown to be unsupported by evidence nor contrary to the agreed evidence. It had been entitled to conclude that the GMF defence had not been made out.
