He was open about them being a protest and not actual pronouns. He wasn't "using the wrong pronouns" for himself.
He was being deliberately provocative. If i worked with young mums I wouldn't put "breast is best" on my email sign-off even if I thought it was factually true.
I have written many posts on here about how I think pronouns are problematic but acting in this way isn't "using inappropriate pronouns" and it's disingenuous to say that was what he was sacked for. He accepted that they could be offensive.
"The only way to challenge this policy, the claimant believed, was
to adopt deliberately provocative pronouns."
I'm not making the argument that either party acted brilliantly, I'm just saying that this wasn't "oh i happened to choose genuine pronouns and management didn't like them".
He was asked not to use them on emails until management had discussed but he said he "couldn't". He expected to be sacked for it.
He also said that using "other" or not using any pronouns "denies me my right to equality in the workplace."
You may think people's beliefs are illogical and laughable but in a professional workplace you can't call them "garbage" which is what he did.
I think if he'd simply have asked what the problem was with his signature, sat back and waited for a reply in writing before using them, he would've had a way better position and could actually have backed the council into a corner. Or asked more questions about them and gotten into an actual dialogue.
The tribunal did have a few interesting points. Worth reading
