The whole salary system is based on pay for developing your skills, and most importantly, the application of those skills. In this way the employees who learn new skills and implement them are rewarded, and those that choose not to participate in the process are essentially choosing to have a compressed salary because they will not be considered for raises. It was noted that it would be difficult to set up such a system in a union environment.
