Tea party brings up images of little girls and stuffed animals around a table to my American mind, but I get what you mean.

My team has a weekly meeting with no management allowed and no agenda. I bring up anything important right at the start, then we go around and give everyone a chance to say what they're working on. No assignments are given out, but people who need help with something can ask and usually get it.

The main purpose of the meeting is to just keep everyone updated on what the rest of the team is doing and give us some water-cooler time. It makes up, in a small way, for the lack of personal interaction we have since going remote. I keep management out because I want us to be free to speak our minds.

The rest of our meetings are more formal and focused and get more actual work done, but without the "tea party" (I'm starting to like that term) we start losing cohesion as a team.
