Explanation:

Retirement is when a person stops or retires working after the service of a certain period of time. Retirement is officially stopping your professional career. It could be because of the age set by the government or companies, the voluntary retirement due to some health issues, work conditions or some other issues or the benefits which a person can avail later.

Retirement could be complete when a person stops working completely or partial when a person reduces working hour in consent with the company. In case of semi-retirement, the compensation is different from full employment as well as full retirement.
