Having both commissions and bonus structure plus my salary I can assure everyone that those commissions and bonuses are a huge motivation to work harder primarily because they are unattained. For those who make the argument that increasing SALARIES motivates people I suggest they think of this: if my bonuses and commissions were guaranteed as part of my salary would I have any incentive whatsoever to work additional hours? What would the incentive be for the facility I manage be to hit target budget? What would the incentive be for me to make my business profitable?
