Excellent posts on this thread, and I am so glad to see and read them. It is heartening that women are at long last taking this invasion, and take over of our rights, privacy, sports, and our spaces seriously.
Before I retired, (6 yrs) the female changing room was for female nurses; female physio, OT, and other female members of staff had their own spaces - more than likely in their own depts.
Doctors in the ED, or ITU, or other high care areas had their own changing areas, and wore scrubs because of the area of their work. Ward doctors wore their own clothes, and 'bare to the elbow', some of the consultants continued to wear white coats, but most no longer do.
I think that the 'Clinical Nurse manager' giving evidence today was an utter train crash during cross examination.
