Informal learning is an important source of employee adaptability and expertise, yet it is unclear how it may be encouraged through human resource management (HRM) practices. In this study, we investigate how opportunities for formal learning may be used to stimulate short- and long-term participation in informal learning. In addition, we examine whether HRM system strength intensifies the relationship between opportunities for formal learning and informal learning. Using a sample of 430 respondents in 52 teams within six Dutch vocational and educational training schools, we adopt a longitudinal design to examine two types of autonomous informal learning activities (reflection and keeping up to date), and three collaborative activities (asking for feedback, knowledge sharing and innovative behavior) over two years. Opportunity for formal learning was positively related to short- and long-term participation in informal learning activities, with the exception of long-term innovation. Moreover, HRM system strength intensified these relationships. Managerial implications of these findings for encouraging informal learning activities at work are discussed. © 2016 Wiley Periodicals, Inc.
