When you are trying to build a friendship with someone, do you only pay for coffee if they did it for you before? Or do you out out a good faith effort and buy them coffee or lunch a couple of times? Companies and employees are the same way. Companies will sometimes overpay someone in the hope for extra effort, or an employee may put in extra time in the hope for future rewards. A win win approach is much better than a zero sum mindset to relationships and employment. My employees who have a win win approach have been massively rewarded over time, those with zero sum mindsets don't last long here or anywhere else and never get beyond entry level.
