Personally, I am convinced that Andy will not get in any professional bother. He is doing exactly what he is employed to do. The bank wants to demonstrate its credentials on social media to the kind of people who look, and he's doing that
I've worked in banking for 20 years and I'm 100% certain that Andy M will be being dragged at speed into someone's office tomorrow.
Several of the big banks are fairly quietly subscribing to the pronoun crap. But all of the big banks are fucking fanatical about reputational damage and risk, especially on SM.
It's the second tweet that he'll be regretting. And God forbid if that actually is Andy M's personal account he started replying from, arguing with customers - that will not go down well at all, plus the other screenshot stuff from his profile. He'll be out the door.
