We draw hypotheses about the factors related to company provision of f
ormal job training programs from diverse theoretical perspectives and
research findings. Using data from the 1991 National Organizations Sur
vey, we analyze a sample of 688 establishments to estimate multivariat
e models. The relationships between employer-provided job training and
organizational size, unionization, and workforce composition are redu
ced or eliminated in most multivariate equations. Employer-provided tr
aining is most extensive in establishments with elaborate internal str
uctures that operate in complex market environments.
