Ethics in the Workplace Part 2

In my career, I have worked primarily in small companies, and unfortunately, they tend to be small minded when it comes to innovation and creative thought. Now, that does not mean these employers were bad to work for necessarily, but if you were someone like me who desires to better the organization and to think "outside the proverbial box", it does not mean you were going to be the golden boy of the organization.
Small businesses tend to be old school. For example, if you have an employee in a professional role working 80 hours per week, the employer believes that employee is deemed for greatness and has so much loyalty to the company. What they do not ask is WHY is that guy or gal working 80 hours a week? Are they working smart? Are they capable of delegating duties to others in their sphere of influence? In other words, if this person is in management, should their #1 priority be developing future leaders? Are they either incapable of leading, or worse, too insecure and not trusting of people to have their office run more effectively, thus saving the employer money?
So what does this have to do with ethics? Well, to me, it is not ethical if a manager insists of "hoarding" his/her responsibilities and not developing future leaders. This will come back to haunt the employer in the future, even losing quality employees to their competitors. How I know this? I worked for such employers who were in this frame of mind. Even some department heads elevated to that position after their predecessor retired, were at a lost for several weeks or months trying to learn what they needed to do in their role. No succession planning killed the department, or at least slowed it down, hurting business operations, if not morale within the department, which in turn, affects other departments.
Ethics is not just a morality method of dealing with people directly, but to be a leader by example, to use coaching and mentoring methods to ID quality personnel, and prepare them to take charge when that time comes. And it will. Problem is, businesses are still in that "machine mentality" that if it keeps running smoothly, why change the motor?
