In some organisation have differentiation in case of age. For the directors and managers usually are older than others that they also have better in leading people in the organisation. In my opinion, I agree about it. The older people in many case have more knowledge and experience than the younger.
Older people usually involves themself to the organisation longer than the younger. It impact to kind in amount of knowledge about the organisation. They also knows about the problems that often happened in it and knows how to solve it with any resource there. The knowledge also can be obtain by getting education that appropriate or suitable to the organisation. Usually directors and managers have higher degree than others. For example, people with degree magister have more competencies rather than people with bachelor degree with the same subject so people whose more competencies gains position more.
Experience has also became important things. Older people usually have more activities done by them. They obtain some routine duty that have must to be finished with their experience. Sometimes, it can create an intuition so when the older people facing some problems they would use their mind to get some solutions to resolve it without getting research it first. For example, people that hiking his job from becoming staff have faced a lot of challenges so they will have promotion as long as they perform in their carier.
The position of directors and managers in many organisations usually held by older people in it. It is caused by having more knowledge (intellegence) and experience (intuitions).
