Remember that time at work when you felt you couldn't take even one more day of directions from those with no experience, the lack of regard for your input, or the complete absence of appreciation for your efforts The aching pit in your stomach that gets harder to ignore, yet you suffer through it, at least until it all spins out of control and you quit, but that's after its negative impact has permeated every aspect of your life. Other than factors such as salary and benefits, one's supervisor has the greatest impact on the contentment we feel in our jobs as well as our productivity. One manager might influence the lives of tens, if not hundreds of individuals throughout their career. Unfortunately, business education today spends far too much time attempting to train future C.E.O.s and too little grooming great managers. Managers that learn to trust their employees and bring the best out in them are not only a benefit to the employee, but they can actually bring greater success to the organizations they work for.
