Earlier quoted context omitted.
If workers controlled the workplace, this is precisely what would happen. It's only because the people doing the work don't control the work that this seems fanciful.
"Worker-controlled workplaces" are rather common in some industries where capital intensity is especially low, such as legal services (with firms being organized as partnerships; indeed, capital intensity is the main obstacle to this kind of structure in other industries). And yet, top lawyers tend to work quite a bit more than the typical worker.
I would argue that the reason for that is that they more directly see the fruits of their labour.
