Recognising that many workers worldwide often face poverty and exploitation, the International Labour Organisation aims to promote decent and productive work opportunities for all. We conducted a scoping review to get an overall view of current academic literature on decent work and precarious work for samples of blue-collar workers. The studies included in this review, focused on empirical research conducted from 2006 onwards, that primarily investigated decent work or precarious work among semi-skilled and unskilled manual workers. The review team used a data-charting form and collected information from thirty-five articles. Most recent studies (2020-2023) were related to the experiences and livelihoods of non-traditional blue-collar workers namely platform drivers and informal waste pickers. Before 2020, the most commonly studied theme related to the experiences of migrant workers. The findings shed light on the experiences of these workers, particularly in South Africa and India and provide valuable insight into their work experiences for further discussion.
