The authors propose research to test the hypotheses that external or basic factors influence the joining process in organizations, and that internal psychological factors are major determinants of the staying process. They hypothesize that pay, company policy, peer relationships, and working conditions are basic motivators external to the individual and act to attract a worker to a job or push him out of one. Internal psychological factors, such as favorable climate, permissiveness, challenge, and equity, are factors that influence job satisfaction and serve as staying motivators. (RA)
