I'm very glad that you have found a sense of community and connection at work. Loneliness and alienation is serious, and fixing it is not easy. I do think that attending groups connected to your workplace is the wrong approach, even if it can benefit you. Perhaps people could join (or start) such groups which are oriented around professionals in an industry who share a certain background, but isn't tied to any specific company? That way if you get fired or need to switch jobs, you minimize that part of your life which is thrown into chaos.
