Fantastic news Christine
The world needs a lot more of this. Positive open acceptance of gender fluidity. A huge leap forward for you, exciting times.
Guess you will be part of getting all your work colleagues on board. Open discussions/meetings to try to overcome mental barriers. Also practical issues like restrooms, changing areas, health and safety, etc.
And yes bottom line is it should not affect ones ability to do the job and progress your career, so discriminatory issues may be real as well.
So happy for you, and hope you keep us all up to date with developments at work.
