We're just asking for the law as set out in the EA to be respected.
It still needs clarification, though, doesn't it?
Any service that segregates by sex and has an exemption applied should ... be segregated by sex (ie, female-only jobs/services/spaces should be only for females, as that is the whole and entire fucking point of them).
I would go so far as to say if the exemption has been applied/invoked and the service/space/job is NOT female only then they are knowingly putting females at risk by labelling a service/space/job single sex when it is in fact mixed sex.
