Purpose--The aim of this article is to examine network-based learning and discuss how participation in network can enhance organisational learning. Design/methodology/approach--In recent years, companies have increased their collaboration with other organisations, suppliers, customers, etc., in order to meet challenges from a globalised market. They form and participate in a variety of different networks in order to improve innovation, organisational learning and effectiveness. These networks can be considered as one context for learning parallel to training institutions and workplaces. In this paper characteristics of and preconditions for network-based learning are analysed and compared with school-based learning and workplace learning. The analysis draws on experiences from an action research project aiming at improving the occupational health and safety work within 11 Danish enterprises forming a network. Findings--Network learning might hold potential for forming an important supplement to school-based learning and workplace learning. Some of the difficulties related to these two learning arenas can be reduced in a network setting, and in that way network-based learning can help building bridges between the two "traditional" learning arenas. Originality/value--Examines network-based learning and discusses how participation in network can enhance organisational learning. (Contains 1 table.)
