Career rainbow diagram is a career planning model proposed by career planning expert Super in 1976. The model divides career development into five main stages: growth stage, exploration stage, establishment stage, maintenance stage and decline stage. Each stage has its own unique development tasks and needs.

In the rainbow diagram of career, leisure people mainly appear in the maintenance stage and the decline stage. This is because at these stages, people may begin to consider retiring, enjoying life and pursuing personal interests. Career planning experts suggest that individuals should devote part of their time and energy to leisure activities during the maintenance stage and the recession stage, which will help to maintain good mental health and quality of life.

Under the function of leisure, people can engage in their own hobbies, such as traveling, reading, gardening, fitness and so on. These activities can help them relax and improve their quality of life, and at the same time, they can also help them establish wider interpersonal relationships.

Generally speaking, in the professional rainbow map, the role of idle people is to help people better balance their work and life, enjoy their personal hobbies and improve their quality of life.
