This research examines the social side of learning among professionals in the fast evolving and knowledge intense field of consultancy. Its first aim is to unravel social informal learning by proposing a new, integrated framework of workplace learning. Its second aim is to explore the role of learning climate for social informal learning behavior among consultants. Our qualitative inquiry using interviews based on the critical incident technique illustrates that consultants engaged in deliberative and reactive learning, thereby indicating a clear intention to learn. The source of learning was often the direct colleagues and direct supervisor, which highlights the relevance of close proximity of other individuals. The consultants mainly learned from others in a passive manner, followed by proactive and collaborative learning. Finally, this study shows that granting professionals responsibility and autonomy in their learning process as well as having a leader who facilitates learning are important elements of a learning climate that enhances social informal learning. We conclude with recommendations for organizations and directions for future research.
