The aim of the article is to determine the impact that different participation platforms might have on employee productivity levels of the lower-skilled non-unionised employee segment of the South African workplace. A firm-based dynamic log-linear Cobb-Douglas production function model is used as it allows for the incorporation of the dynamic characteristics of the non-unionised employee segment of the South African workplace. The main conclusions of the study are that, i) the positive productivity spill-over effects of a formal committee participation platform in the lower-skilled non-unionised employee segment of the South African workplace are superior to non-committee participation platforms and, ii) a more dispersed racial participation rate, greater gender spread and a dynamic age spread for non-unionised employees are important contributing factors towards the enhancement of higher productivity levels for lower-skilled non-unionised employee participation platforms.
