A woman is forced to leave her job because her employer operates a practice that staff must work in a shift pattern which she is unable to comply with because she needs to look after her children at particular times of day, and no allowances are made because of those needs. This would put women (who are shown to be more likely to be responsible for childcare) at a disadvantage, and the employer will have indirectly discriminated against the woman unless the practice can be justified.
An observant Jewish engineer who is seeking an advanced diploma decides (even though he is sufficiently qualified to do so) not to apply to a specialist training company because it invariably undertakes the selection exercises for the relevant course on Saturdays. The company will have indirectly discriminated against the engineer unless the practice can be justified.
