The Productivity Commission is currently conducting a major inquiry into the framework for regulating workplace relations in Australia. Researchers from Adelaide Law School’s Work and Employment Regulation research group have joined leading academics from three other institutions to prepare a submission to this important inquiry, which is due to be concluded by the end of 2015. The submission, for which research group co-director Professor Andrew Stewart was the lead author, emphasises the need for caution before embarking on major reforms to the current Fair Work regime. It stresses the absence of compelling evidence that regulatory changes would deliver superior economic and social outcomes, the potential costs of reform, and the potential to pursue improvements in productivity through other means (such as improving management and leadership in the workplace).
