My company’s culture leans toward blurring the line between “friend” and “co-worker.” That has its pros and cons, but as we get bigger I see it being more of a bad thing than a good thing: people are unwilling to point out poor performance, etc., and are way too concerned with everyone’s feelings. (My motto: If you don’t do your job, screw your feelings!)
Personally, I’m not against the idea of becoming friends with a co-worker (in fact I met my best friend when we worked together 5 years ago), it just doesn’t happen very often. Partly because I’m picky about who I become friends with in general, but partly because I think that the line can be a tough one to cross: you never really know someone until you spend time with them outside of work, but if you find that you don’t really like them at that point, things can get complicated (hurt feelings, some people’s inability to separate business from personal, etc.).
That said, I’m pretty social at work: I go to welcome/birthday/farewell lunches, I have a few drinks at the occasional happy hour outside of the office, I go to all of the holiday parties and company picnics, there are a handful of people I’ll sit and chit-chat with during the day, etc. I like and get along with most of my co-workers, I just don’t think we’d want to hang out on weekends.
Also, it’s gotten harder to transfer work friendships to real life as I’ve gotten older: these days, if I meet someone I seem to click with, chances are that they have a husband/wife and probably kids. They have their lives and routines, I have my life and routines, and there just aren’t as many chances to wind up hanging out and getting to know each other. I value happy hour for that reason (it’s the outside-of-work setting that’s necessary to getting to know people, yet without any pressure), but it doesn’t happen with any regularity.
The only thing I actively refrain from is chipping in for personal events: baby showers, weddings, etc. I’ll pay for myself at a welcome/birthday/farewell lunch, and will even chip in to cover the honoree, but I won’t chip in for any kind of gift. I don’t feel obligated to give gifts to people who are not my personal friends, and a long time ago I stopped caring about what anyone thinks of me because of it. I’ve broken that “rule” once at this job, when my supervisor completed her EdD earlier this year: people don’t go around getting doctorate degrees like they go around getting married and having babies.
(That wasn’t the real reason, but it’s true!)
What kind of job do you have where your co-workers could make that decision for you if they did know what your commitments were? Hell, if I want to take a day off to sit around the house in my PJs and watch old X-Files episodes, not even our CEO could tell me not to!
