Work is a turbulent field closely interconnected with all aspects of life. It is expected that the twin transitions (green and digital) will profoundly change labour markets and skills, in response to which social and economic cohesion must be strengthened. In this raplex (rapidly changing and complex) environment, it is required that people, trade unions, governments and international institutions first understand the emerging challenges and then take appropriate policy actions to address them. For that the three work/tech 2050 scenarios produced by the Millennium Project provide a comprehensive and valuable basis for longer-term thinking and highlight a number of aspects that require coordinated global policies.
