I had a job like this for about 2 years. There's only so much content you can consume before you really just start to lose your mind. Also losing skills is a real thing. And to be perfectly honest, when compensated fairly, some of us enjoy our careers.
I'd rather be at home where i can enjoy my life as i choose if I'm not working. End of it for me. I get it, paid to do nothing but i just don't like doing nothing. Not saying i want to beat my body or mind up non stop but full stop, hurry up and wait... No thanks.
There's more in person hurry up and do nothing jobs than work from home positions, and I would imagine most people complaining are not working from home, or have to maintain availability showing in a chat program, or are just busy enough to not be able to get into what they want to be doing.
