Explanatory theories of retirement: There are many theories that have been formulated to try to understand and explain the phenomenon of retirement. Here is a presentation of the most important theories (Tanbak, 1416: 85). 1- The reciprocal theory: 2 - This theory is based on the principle of the principle of exchange, so that the individual as much as he takes because this individual when he interact with others is thus achieving maximum benefit at the lowest cost, and therefore the elderly provided their children care from birth until they reach the age they rely on themselves and In this sense, the strength of this theory lies in the fact that all kinds of social interaction can be included in this perspective, but what is difficult is the principle of benefit and cost or profit and loss. There is a clear difference between people who succeed. Hurdles It is against the principle of reciprocity, and this is not a condition that parents be something great to be answered by children especially in our Muslim community, which made the care of parents originally worship and close to God. Activity theory: This theory is called Friedman, Hevigrst, and Miller. It is based on adaptation by older people to retirement. They must participate in social activities and have alternative roles to compensate for those roles they have lost in retirement. Some have a source of income and may mean to others a source of pride or creativity or service to others. Also, when the individual loses that, he depends on his ability to find alternatives through which he achieves the personal goals that the previous work has achieved for him. This theory was applied to American society, and its results were limited. It was found that the relationship between the satisfaction of living and the activity in compensating the roles is weak, which makes the hypotheses of this theory not deep. - The theory of separatism: This theory emerged in 1961 by Kemmuhenri. It is called the theory of withdrawal or disengagement. It is based on the assumption that the individual is a group of social relations. As he grows older, he withdraws from social activities and separates them from obligatory activities. The same individual and society. Criticism of this theory is as Achley states by making society's rejection of older people inevitable and that older people, even if they give up some of their roles, do not give up their roles. Continuity Theory: The theory on the basis of criticism of the theory of activity, separation or withdrawal and go this theory to be adapted retired depends on finding roles similar to the roles that the individual practiced before retirement as he said in that Othley, and that older people cling to what traditionally in their lives, trying to be their lives after retirement is similar to a large extent to their lives before retirement, and that the majority of them invest time and effort in the pre-retirement stage for later, and reduces proponents of this theory of negative associated with the retirement of effects, due to the knowledge of the individual prior to retirement is inevitable and has friends and relatives From retirement have been referred to and therefore be understanding that this situation has become mainstream, according to this theory, the systems allow for the gradual abandonment of some activities in general. 5. Crisis theory: This theory focuses on the psychological and social compatibility of the individual and that individuals who give utmost importance to work in their lives and earn them a professional role determines their relationships with others, the retirement represents a crisis so that the elderly feel fear and anxiety and reflect on the psychology, and tried this theory to identify the following points: • Work, value and satisfaction of the individual after deprivation. • The behavior of the individual after retirement. • Relationship between commitment to work and dislike. • Consistent behavior of the retiree. In their interpretation of this theory, however, the researchers were divided into two groups: The first team: - I support that the individual after his retirement to consider himself a bit of inferiority and his relations negatively affected with his family and society. Second Team: It is considered that there are several factors that negatively affect the individual and not only the retirement, there are economic, social, health and others.
