So recently, I was sitting with a couple co-workers and my boss and one of my co-workers made a remark to my boss about being excited for a party (a brewery tour) that my boss had invited him too. My boss got very quiet and responded to co-worker A about the tour, then very sheepishly said to co-worker B and myself something along the lines of:
I'm not sure if you guys want to come, but uhh...I guess you guys can come...we're getting a brewery tour together.
My boss knows I like craft beer as discussed it before while getting after work drinks one time right after I started as a "Welcome to the team" sort of thing. Since then, I haven't done anything with any of my co-workers. Originally, I assumed it was because everyone had their own lives (most are married with kids and I'm 25 and living alone), but now, I think it's more that I'm being excluded from events and social get togethers.
I didn't say anything and neither did co-worker A or B. I want to be included in the comradery so I can feel like I have something more than a "boss/worker relationship" or "co-worker/co-worker relationship", but I don't want to be there if it's a "pity invite".
How do I approach my boss and other co-workers to let them know that I am interested in socializing with the team outside of work?
