The job survival of 1,736 newly hired workers across a variety of organizations is examined. Voluntary and involuntary turnover are analyzed separately over the first 29 weeks on the job. Moderate support is found for a theory of job survival which distinguishes between the effects of job attitudes on voluntary withdrawal and job performance on involuntary withdrawal. Organization related factors such as pay and training are better predictors of job survival than are individual variables such as race, sex, age, and education. Copyright © 1979, Wiley Blackwell.
