I don't know where you're from but where I live "guys" is a completely neutral term for any group of humans. My wife used it today on a call to three other females.
Imagine you took a job somewhere where in their region your field was overwhelmingly female dominated and “hey girls” was considered gender neutral. And you already felt pretty excluded being the only guy on the team and one of less than 10 guys in the whole company. And they’re not purposely excluding you but they didn’t even think that having outside of work team bonding of getting mani-pedis might be uncomfortable for you. Or the fact that all their reaction gifs and references in Slack are of girly shows you’re never seen. And so the fact that at every Zoom call, every company wide meeting it’s “hey girls” just reminds you of how excluded you already feel. So you being it up and ask them to maybe use a different phrase that is a little more gender neutral to you and they brush you off, say that “girls” IS gender neutral and that it’s not their problem.
You know what does feel super awkward though? When someone says "hey guys" in the chat, and then immediately trips over themselves to "correct" themselves, because they're afraid they've hurt my feelings or that they will be called out for uttering "wrongspeak". It's absurd to assign ill-intent to someone for simply using a slightly different dialect of American English than yourself. I'm from the south, so I say "y'all", and nobody gives me a hard time over it.
Also - who cares if your coworkers have different tastes in things than you do? You're not at work to talk about TV shows or trade gifs. The whole "you should bond with your coworkers like they're your friends" thing is a toxic myth that companies promote for purely selfish reasons.
And It doesn’t really bother me that I don’t have many boyish interests and so my entirely male rest of my team don’t talk to me very much about TV and movies or their hobbies but I still make an effort to be their friends because like we’re a small team and spend all day together. Being friends with my coworkers is honestly good for my mental health, the company be damned.
The team I'm currently working with are exclusively of Indian heritage, I'm white. They often talk about Bollywood films, what they did for Diwali, etc. Should this make me feel awkward or excluded?
I don't really care if the company I work for is overwhelmingly anything. I usually manage to find some common ground with any person on an individual level. I don't really consider what the identify as, or what social grouping they've been deemed to belong to, as having any significance.
