In Britain, it's definitely something you need to watch out for. > indirect discrimination - putting rules or arrangements in place that apply to everyone, but that put someone with a protected characteristic at an unfair disadvantage (from https://www.gov.uk/discrimination-your-rights/how-you-can-be-discriminated-against https://www.gov.uk/discrimination-your-rights/how-you-can-be...). There have definitely been cases around aspects of part-time working which have been held to be indirect discrimination because men are (were?) overwhelmingly full-time and women not. It is also possible to make a justification defence for indirect discrimination, though I don't know 'how good' your justification would need to be.
