Exactly. I am referring to knowledge workers, and how profit sharing may have a negative impact in productivity. This is what extensive research has shown to be true.
However, for physical or algorithmical labor (if > then tasks) profit sharing does work indeed.
My point is that for knowledge workers — an increasing part of the workforce, given that even if-then jobs like CRM consultants are transitioning to knowledge-working approaches — we must be aware of the need to find alternatives. ☺
