The sign of the bleeding obvious: that 'policy' has been written by political activists with a very specific agenda, which includes the destruction of women's sex based rights.
This might as well be their BAME policy written by UKIP.
If written by employed staff (who wrote it themselves as opposed to cutting and pasting from a political lobby's guidance) then the staff are political activists whose training has been in political indoctrination and not in actual law, and questions have to be asked about whether being an activist can be compatible with holding a job that involves responsibility, ethics, impartiality and actually focusing on the job rather than how it furthers the Glorious Day, Brothers.
And the advice is now not only illegal but actively offensive and derogatory of a large number of staff and patients. I'm sure Ben and Naomi would adore to get their teeth into it and any other trust that is still permitting this kind of nonsense. If staff cannot change gear then they are going to have to be removed via competency proceedures with a lot of questions asked about how they got through the recruitment process in the first place. The government is seriously going to have to roll out national training on women's rights, the law and basically deprogramming to undo the false information and indoctrination they allowed to happen through lobbies they were funding.
