Epistemological beliefs are fundamental assumptions about the nature of knowledge and learning. Research in university contexts has shown that they affect the ways and results of student learning. This article transfers the concept of epistemological beliefs on workplace learning. The basic assumption is that employees epistemological beliefs affect whether they perceive their workplace as learning environments. A study was conducted in which the interrelation of employees epistemological beliefs with their appraisal of the workplace as supportive for learning was investigated. Additionally, the role of professional hierarchical levels concerning work-related epistemological beliefs was analyzed. No significant interrelation between epistemological beliefs and workplace appraisal was found. Groups from different professional hierarchical levels did not differ in their workplace appraisal. Consequences about future research about the role of epistemological for workplace learning are discussed. (Contains 1 table.)
