I feel so afraid and sad for trans people now. The genuine ones have a lesser place now. What have they done wrong? Nothing!
I don't think anything has changed though. 'Genuine' transpeople can carry on as before. The ruling hasn't made it illegal for them to use the Ladies (assuming they are TW), just clarified that they are male, which they must have realised given that they made the choice to transition.
I can see that in the (unlikely?) event that someone complains to management that there is a TW using the Ladies at work the decision of any tribunal might be to suggest that they use the Gents. But the reality is likely to be that this won't happen, as people are, on the whole, tolerant.
More importantly though, there may be implications for males getting posts which are legally allowed to be ring-fenced for women only, such as delivering personal care, or rape counselling. Much as this may be worrying for a very small number of transpeople who work in these areas, IMO it is a good thing that women can be assured that when they ask for a female carer they will get a woman, not a TW.
