It kind of already is in a lot of places. Hourly workers get refused enough hours to be considered full time workers, and are then forced to work multiple jobs for sub living wages and no benefits - I think the push for services like UberEats is the natural evolution of this, allowing every worker to work for every corporation simultaneously while the corporations collectively pay the workers subsistence wages.

But for things like tech employees, where there is a lot of scientific data to back up increasing productivity by reducing hours, I could see the neoliberal push be to reduce hours and cut pay. Then once the tech workers have more free time and also need more money, their demotion to a lower tier of wealth will be complete when they all start looking for side work. Whether by this road or another, it's a process that will inevitably happen as the current tech bubble fills in, the same way it did for the physical trades back in the 70s and 80s.
