In a world in which traditional hierarchy slowly but surely is substituted (or complemented) by new forms of organizing, the development of strong organizational relationships has become even more important. Trust is a fundamental aspect of these relationships. But how do we form trust? More specifically: how is trust built (and sometimes broken)? Over the last 20 years, research in social sciences has given us ample understanding of the underlying components. In this evidence based workshop we will explore, make sense and experience the latest insights on trust development.
