HR department at a previous workplace was like that. All women, all friends, all worked with each other or were relatives of someone... their personal lives were entirely intertwined with work. Most weren't at work most days and this was when they had a no work from home policy years ago. Loud personal calls all day long.
I wasn't even in that department and the drama that came from it was exhausting.
They would often take longer than their allotted meeting time in meeting rooms because after their meeting someone in there was crying ... why? Who knows... it was only known within that group. It just kept happening over and over... Along with folks storming down the hall all upset, again who knows why. Now stuff happens sometimes at work, no big deal, but running into these exhausting people couple times a week really takes a toll on you.
When were moving offices the tech support team was seated next to HR. At one point HR invited the both all of tech support and HR (at least those at that building) to a meeting to discuss why tech support wasn't "social enough" and "spent all day in their cubes", I duno maybe they're working... Thankfully that got cancelled quickly after a number of people (me included) noted to a VP that "No matter what the reason, there's no way this meeting ends in anything but a total disaster."
Then came the litany of complaints that HR sponsored events (where HR planned everything to HR's preferences) were not attended enough by the tech support team and how much work they put into it and so on... I even left those events early because it's a lunch event and I don't want to eat veggie pizza only, I can only take lunch for so long.
