Childcare, gardening (with surplus to share, maybe!), elder care, home improvement projects. Art, writing. Collecting stories and genealogies for family. Knitting and sewing.
People do tons of work even when they’re not being told to, in my experience. It’s sometimes “worth” a ton less than the time they put into it, and they’re usually making little or no money at it, but that doesn’t make it not-work.
