Retirement Age

Retirement is the point where a person stops employment completely. The "standard" retirement age varies from country to country, but it is generally between 50 and 70, according to the latest statistics, 2011. However, for a long time, people have got into an argument about whether the age of retirement should be increased or reduced in their own countries.

There are several arguments for allowing older people to continue working as long as they are able. Many people think that older employees have a large amount of knowledge and experience which can be lost to a business or organization if they are made to retire. Besides, older employees are often extremely faithful employees and are more willing to implement company policies than the young. A more important point is regarding the attitudes in society to old people. To force someone to resign or retire at 60 or 65 indicates that the society does not value the input of these people and that effectively their useful life is over.

Allowing old people to work indefinitely(无限期地), however, is not always a good policy. Some people took the strong view that age alone is no guarantee of ability. Many young employees have more experience or skills than older staff, who may have been stuck in one area for most of their working lives. Having compulsory retirement allows new ideas in an organization. On the other hand, older people should be rewarded by society for their life's labor by being given generous pensions and the freedom to enjoy leisure. They can have time to do whatever they like, that is, they can have their own plans or roles and achieve their retirement goals.

With many young people unemployed or frustrated in low-level positions, there are often calls to compulsorily retire older workers. However, this can affect the older individual's freedom—and right—to work. In my opinion, giving workers more choices over their retirement age will benefit society and the individual.
