In my opinion every work environment gets better when people put in effort to get along. Be the change. You and your colleagues will be happier when you know each other and have something to talk about besides work.
Getting along with people is done by keeping a good balance between being interested in what they are doing and talking about stuff that you are enthusiastic about.
For the first one you can ask questions about their weekend, vacations plans, hobbies, family or pets. These things will normally be the things that everybody is enthusiastic about. Then later you will have something to refer to. If you colleague plays tennis every weekend, you can ask her if she won last weekend. Or when it’s getting close to your colleagues’ vacation, you can ask him if he is already packing or looking forward to the trip.
But only asking questions will lead to an awkward conversation and sometimes people have little to say. It’s fine to start talking about things you are interested in, also out of nowhere. I shared my plans to go to the movie the parasite to my colleagues and all of us had an intense conversation about movies. I ask if anyone is watching the same tv-show, especially if there was an exciting episode recently. You find more what you have in common with your colleagues, if you share more of yourself. So, if someone ask what you are doing this weekend, share the plans that you are excited about. Even if it’s binging The Office for the third time on the couch!
