Work for a NHS Trust. Equality & Diversity training (which is mandatory for all staff) heavily references the Equality Act (understandably) and the 9 protected characteristics. Apparently gender is one of the 9 characteristics, not sex. Training then refers to gender throughout.
I emailed relevant department to point out the mistake and have been told gender and sex are the same thing.
Just want to scream. And share my frustration. I’m pretty sure I knew the difference from taking GCSE sociology as a teenager many years ago.
