Toxic work environment..

What do you do when you truly dislike your work environment? My boss is very passive aggressive. My coworkers are cliquey.. I feel like they are a team and then there’s me. I won’t name any specific race, but, they are all the same race, and then there’s me. We work in a HUGE organization in the city. There are many of my race in the organization as a whole, but In my department, there is just 3 of us. I don’t think that my race is the reason, but it’s just makes me feel like it’s cliquey. they have little inside jokes with my boss, I’m constantly left out of work events. One of my coworkers makes comments about me “not doing extra work” but pretends to be my friend. All I do, is come in, do my work and leave. But I feel like this will hinder me from moving forward or getting any type of increase. I come from a company that was very close knit, people knew each other on a personal level and you got a raise of 3-5% every October plus a Christmas bonus. Here, we don’t get yearly raises, pto is very limited and there is very little work life balance. I’m at point where I don’t feel like an asset to the team and I’m wondering what was the turning point. I don’t feel like my team or my boss like me. Sometimes I even try to evaluate myself and wonder like what I could be doing differently, and second guessing my actions. I just started here 5 months ago and I don’t see myself being here long term. What are your thoughts?
