This paper uses a sub-sample (N = 5,800) of a unique data set on work and lifelong learning to develop the learning dimension of the Job Demand-Control model (Administrative Science Quarterly [1979] 24:285). The model is expanded by including three distinct learning behaviors to allow for a complete assessment of workplace learning. Worker control is also expanded to include often confounded dimensions of Social and Technical Control. The results confirm that different types of learning are related to different determinants and that Social and Technical Control are key factors in learning participation.
