You don't have those things when working remotely. You need to foster social relations at work too; after-work socializing is not a substitute for a collaborative work atmosphere.
You don’t “need” to foster social relations at work. They will naturally arise as people work together. This idea that we need to turn the workplace into a big “family” is nonsensical corporate propaganda pushed by HR departments primarily staffed by women. I promise, most men don’t give a single fuck about “fostering social relationships” at work. The guys I have respected and became the most friendly with at work have been the ones I’m in the trenches with, designing, building, etc. I don’t need to know what Susan in HR’s kid did over the weekend, it’s legitimately useless information to my entire life.
I’ve got ~90 years on this planet at best. I’m not interested in wasting 1/5th of my working career in meetings, listening to people I don’t even know, telling me personal details about their lives I will not retain for more than 5 seconds. To me, it’s genuinely insulting to my time to waste it with these pointless fake displays of familiarity instead of getting to the work at hand and ending the meeting early.
Why would they want to be in trenches with you, collaborate on a project, start a company, or otherwise stick their neck out for you, if they don't know you? They'll pick someone they enjoy rapport with.
No thanks, I have my own hobbies and friends. Activities that primarily benefit work, including team building exercises, should be during paid company time.
