With the development of technology, the decrease in weekly working hours and the increasing awareness of human beings, the leisure time we can use freely is increasing rapidly. However, as leisure time increases, the problems of managing it increase. Pioneering studies have preferred to classify the factors that limit the effective and efficient use of leisure time into certain patterns. However, the constraints that individuals face in making the best use of their leisure time are too broad and personal to fit into any mould. Leisure constraints, which may manifest in different ways for different individuals, may cause problems in the management of leisure time and may also have a negative impact on the phenomenon of leisure time. From this point, the concept of "unmanageable leisure time" emerges. In this context, in-depth evaluations were made in order to better define the concept of unmanageable leisure time, which is one of the important individual and social management problems of our modern age. The study aims to make a descriptive contribution to the literature and researchers by addressing it conceptually.
