"Making friends at work or coworking with friends can help support relationships and fun." And one day, it just isn't fun. Who do turn to for support? Will your friends be there when you quit your job? And to the contrary: If your friend, family and co-workers are all the same, how will you cope at work when going through a divorce?

I'd say there's a meta-balance to be had here. If you over-integrate your "buckets", you're removing redundancy from your life.

Nobody is suggesting that you only make friendships at work or that you don't have any friends outside of work. That's a bad idea.

It is self-defeating to avoid becoming friendly with anyone you do work with, though.

And for what it's worth, my work friends were indeed very supportive when I quit past jobs. Leaving the job didn't end our friendships.

The only interactions I have had from past coworkers in 10 years of working full time is one of them occasionally likes a post I make on LinkedIn. YMMV.
