Idk about pub vibes. But work culture fit is always a factor when hiring. If the person hiring you doesn't like your vibe, you ain't getting the job. Sometimes that extends to the whole team and your 3 month probationary period will heavily depend on you fitting with other workers.

i knew a couple Russian born women in the IT world of Washington State in the 1990s. One was very much like the woman described here. She ultimately changed careers because she couldn't vibe with the work culture and her appearance caused unexpected attention. No doubt she was amazing to look at and sweet but very reserved. The other lady was also beautiful and knew it could be a distraction so she just made sure she was in charge so it wouldn't become an issue. That meant changing to fit the work environment. She became very outgoing and dedicated to being a top performer so she could move up and ensure she would get respect for her work and also use her appeal to get the extra advantage.

It does boil down to fitting in and willingness to change. If you can't be in the team spirit you can't join the team.

Yeah sure, if someone does not fit in with the team and it's a rather social job, fair enough.

But using something arbitrary like favouring some sports team, even though this served as an example, this doesn't seem to be either a significant nor sufficient decision basis.

... because it's a team of dipshits?

So fire the dipshits instead.
