I also find that team building can be stressful depending on how your work is fluctuating. If it’s under a heavy load, then it feels frustratingly like a waste of time when you could be getting things done. While I think team building is important, I think it’s so hard to get right. Frankly, the best teams I’ve worked in are ones where everyone had a similar work ethic.
On the other hand, companies/teams shouldn’t force you into such high workloads that being human with your coworkers feels like a waste of time. You’d be surprised how many wasteful discussions, long meetings, bike shedding debates, and managerial overhead melts away when people talk the same language and understand each other’s quirks.
Was that snark or is the person just tired? Are they rude or busy? Are they slacking or dealing with a newborn? So much easier to understand nuance when you know the people you work with.
