Why the fuck would anyone schmooze to a boss/company who can fire you at anytime? At-will employment cuts both ways.
Not so much the boss, but I like my coworkers and enjoy an occasional night out with them. This might shock HN but not everyone despises their job and not everyone hates the people they work with. Company occasionally runs an optional dinner/entertainment night with food and drinks paid for. And I'm happy to participate.
And… if they truly want to see me ? Select a work day, do it during the work day. Current job host a seminar during the work hour, with a one night out on a hostel on Thursday. Not a week end.
