To answer some of your questions and add some thoughts.
We don’t know when DU started with Fife HB. We are guessing that he started at an FY1 in august 2021 - that’s the first year of a 2 year training programme that he needs to complete to be fully qualified as a doctor.
He claims that he was “ fully out as trans at work “ by August 2022, when he was an FY2, a second year trainee. So very junior, still wet behind the ears.
Most junior doctors with half a brain have worked out that the nurses with 30 years experience usually know a great deal more than they do and it’s wise to treat them with respect as valued colleagues rather than pick fights and try to play oneupmanship games with them.
They also know that most nurses are team players and will stick together, that anyone who has worked there for 30 years will probably be well liked and well respected, so it’s probably smart not to piss them off.
That’s if they have half a brain of course. As we have seen, not all do.
You asked about paperwork - NHS Fife have many of bits of paper to check before someone starts work - graduation, Registration with GMC, birth certificate, PVG checks ( police checks) , vaccination records , references, proof of right to work in the Uk / citizenship etc
Re GRC - As you say, given the time line, we assume that DU didn't have a GRC at the time of these events. We also conclude that he doesn’t have one now or he would have mentioned it in the belief that it would help his case “Look here’s proof I’m legally a woman as well as biologically a woman”.
One of the consequences of this case for DU is that he has outed himself as a rather difficult character, to say the least. This is going to limit his career opportunities ( that’s if the GMC doesn’t put restrictions on his registration, given that he can’t tell if patients are male or female and that he has stated in court that he would to treat Patients without their consent ) .
Maybe he could get hired with the likes of Gender GP 😂. Or in some area of public health medicine where he only has to interact with other True Believers. But no one is going to ever hire him in a role where he has to work in a team, which is most jobs in medicine.
Im guessing he wasn’t an academic high flyer, given his jobs to date, so he's probably not smart enough or qualified to get an academic post.
I also note that unlike most of his class, DU did NOT attend his graduation ceremony in June 2022 ( there was no in person ceremony in 2021 due to covid rules ). Which is odd given that he was obviously living less than an hour away. Draw your own conclusions.
