We first compare and contrast current conceptualizations of workplace flexibility in order to arrive at a definition in harmony with its contemporary use: ‘the ability of workers to make choices influencing when, where, and for how long they engage in work-related tasks’. Next, we situate workplace flexibility in its theoretical contexts to provide researchers with a clearer understanding of what workplace flexibility is, what its mechanisms of operation are, and why it may be related to other concepts. Finally, we present a conceptual framework of antecedents and consequences of workplace flexibility, including illustrative examples of several basic associations from the peer-reviewed literature.
