You shouldn’t have to take a cut in pay for this. Productivity has increased and the benefits of the productivity increase has only gone to the ultra wealthy.
But negotiating only for higher wages per hour and lower hours as a package deal could make it harder to get either. It probably depends employer to employer, but doing both at the same time would be hard to make them do.
Which is why we need to build class solidarity, unions, and strike. A hundred years ago, people fought for everything they could get. They didn’t say “safe working conditions or a 40h work week.” They said, “we want all we can get.”
I’m a programmer, and it’s very different from hourly work. Realistically, any programmer is coding for like 1-2 hours a day. There are meetings so we understand the problem we have to solve, and a lot of time thinking through the problems and architecture solutions. We’re not sitting there typing for 8 hours a day, or at least those are the ones getting burned out. Realistically I’m working like 30 hours a week already, with only 10 hours being real coding, the rest being talking, researching, learning, and pondering. Maybe I’m lucky I work somewhere that that stuff isn’t seen as slacking.
Ugh. I once did some independent programming and the guy insisted I do it in front of him because it involved his proprietary data. So much griping about the time I spent looking at documentation or referring to coding assistance sites like Stack Overflow. I quit on day two.
