Woah, I do not spend the majority of my time at work! For a given week I am awake for approximately 112 hours but I only spend 40 at work, so less than 36% of a given week is spent at work.
During work I am usually too busy, uh, working to really socialize. I mean, I'm friendly, there's water cooler banter, but I've got work to do.
I socialize plenty, just outside of the office with people who aren't my colleagues.
I've personally seen excessive fraternization backfire badly. You also realize, once you've been around the block once or twice, that friends you make at work are very shallow friendships 99.99% of the time.
Here's an argument for boundaries at work: https://hbr.org/2003/12/in-praise-of-boundaries-a-conversati...
>You don’t have time to make friends if you’re out socializing every night with pseudofriends. And on a smaller scale, the same is true in business offices. It is a terrific imposition for a business to ask people to give up their weekends and their evenings for unpaid work. I get these pathetic letters from 70-year-old retired executives who say, “I worked for 40 years in this office, and everybody loved me. They gave me this huge party when I left. And now nobody calls me. What happened?” What happened, I say, is that your colleagues aren’t your friends—and they never were.
