Do you assume to know what the ethics of all MBAs are? It's often misconstrued that the goals of the manager or organization are the goals of the individual employee. Individual employees are at the bottom of the food chain because they have the greatest weaknesses when it comes to management and leadership. If they didn't they could prove themselves through success and level up. An employee is hired to do a job. If an employees goals and ideals are not in alignment with the origanization that needs to be corrected through effective leadership or that employee needs to find another job. That applies to all levels of an organization from individual contributor, to manager, to leadership roles.

A disgruntled employee indicates a problem that is not being addressed and solved by managers and leaders. That doesn't mean the employee is right or wrong or that the manager is right or wrong. Weaknesses are in individuals and occur at all levels of business. A poor employee just lacks self-awareness, knowledge acumen and the correct strategy for solving the problems, whatever they may be, at whatever level they are. This is what effective leaders address.
