Very glad her employer decided not to punish her further. But this is still an awful situation overall.
They already issued her a final written warning and a referral to the NMC for "misgendering", gave her no support for the racial abuse, and dragged her through this disciplinary process, so the damage has already been done. I hope she has a good case at tribunal and takes them to the cleaners for this.
Also there's no indication that the "preferred pronoun" policy, nor the punishments for not pretending that men are women, have been remoted. This could happen again to someone else and probably will.
