Trade union and Industry 4.0 implementation: two polar cases in Brazilian trucks manufacturing

Purpose This paper aims to discuss how trade union leaders deal with the implementation of Industry 4.0 (I4.0). The study is circumscribed to the Brazilian automotive sector and came from a human-centric (Industry 5.0) concern related to issues such as organisational learning, knowledge, innovation and workplace learning. Design/methodology/approach Case studies in two truck plants related to union participation during new product and process implementation based on Industry 4.0. Semi-structured interviews with union leaders from both plants were conducted to determine the subtle similarities and differences between the two polar types. Findings The findings pointed out that human resources and workplace learning must be reviewed to prepare workers to face I4.0. Four themes are explored: modernisation origins; negotiation process; workers’ concerns; and results and lessons learned. The findings highlight concerns about employees and job loss; replacement of workers by technological devices; workplace learning and the trade union perspective; and influence of the country’s economic situation on I4.0 implementation in social systems dependent on worker tacit knowledge. Originality/value This paper presents labour union leaders’ perspectives related to the impact of I4.0 and contributes to a better understanding of industry-worker workplace learning.
