This paper studies the use of Group Recreation Activity (G.R.A.) in the development of organization. G.R.A. is a skill usually used in an enterprise to improve interpersonal relationship, to relieve employees¡¦ working pressure, and to promote the morale of the employees so that the company will be more competitive. Besides literature review, the questionnaire investigation is applied before and after G.R.A. is implemented, in order to examine the effect of G.R.A. The study reveals that, at large, G.R.A. is helpful in raising the working efficiency. G.R.A. can promote workers¡¦ enthusiasm for their jobs, relieving employees from heavy pressure, improving the communicative ability of the group leader, fostering cooperation inside the company as well as strengthening the loyalty of the employees to the enterprise. The study also discloses a fact that G.R.A. cannot promote the employees¡¦ satisfaction for their salary. What employees care most is not G.R.A., but their income. In other words, the application of G.R.A. will work after the employees are satisfied with their wages, i.e., their basic need of living.
