One of my coworkers started complaining that I didn't wear a mask on a Zoom call, because I might "infect the people coming into my house". That so-called person is my house cleaner, and we're both triple vaccinated and are fine not wearing masks. Should I tell my coworker to mind their own business?

Sounds like a Karen. I would certainly put them in their place unless it's absolutely crucial you retain a good working relationship with them

Yes, tell them to mind their own business!

I too like to partake in creative writing.

People like this are why we’re in day 800 of two weeks to slow the spread

Literally none of their business how you conduct your life at home

lol what? Wow (and I’m triple vaxxed and support public mask mandates)

Lol, you could go camera free and tell them that you know they get alot of anxiety seeing other people/your background so to make sure you're both comfortable you'll help them out 😄. Seriously though, it's I'd your right to conduct your home as it makes sense for you, you're doing so safely, don't have to justify it to this nosy person. Also really shouldn't announce your houekeeper's medical information, it's not ok for your coworker to even insinuate that it is appropriate. Set the boundary, but at the end of the day it really does sound like the person may be struggling. Maybe ask them if they're ok and check-in from time to time, before diving into work, if you're feeling generous.
