Thanks everyone for the ideas/discussion. To give a bit more context: it was a whole-team discussion, and I wanted to refer to a subteam, and ask "hey, you guys are the ones maintaining this system, right?". But then I realized I was talking to a lady, and "guys" might be not OK, so I switched to "people". That wasn't a good choice 🤦♂️
"you folks" as @ellotheth suggested would work, I guess? But "y'all" would address the whole group instead of the subteam, right?
