If the "get paid to walk" programmes [1][2] were an inspiration for this, it's mostly retirees and students that will do and try to game this [3].

I'm in the Bay Area. It's Sunday morning and I'm working becasue I still need to pay for food, rent, and enormous medical bills and don't want to get fired, and I got yelled at by my director this morning on Slack because I'm not delivering fast enough despite squashing 12 months' worth of work into 4.
I don't have time for books. Finding time for even exercise is hard.
EDIT: while more common in the US, if you are actually regularly working weekends, look for a better job. In my part of FAANG I rarely have to work weekends, although the occasional crunch time can happen.
