I beg to differ. Everywhere I've worked, people have despised the waiting built into the processes they have to conform to. Many roles are constructed so that they're actually two roles: one is pure productivity, with clear goals and deadlines. The other is some sort of service role where you're at the beck and call of clients who could waltz in whenever, defined less by your productivity than by your availability (which is always meant to keep you in an workplace for 6+ hours). Switching between roles is aggravating; effectiveness at one kills the other, to some degree. Most would rather just do one at a time, and be paid for either the time sacrificed or the work completed, at a dignified rate.

But that would cut into C-suite bonuses and dividends.
