Artificial intelligence (AI) systems are increasingly being used across various industries. This FES-UNI Europa report presents the current situation in collective bargaining regarding the use of AI-related tools by employers vis-à-vis workers, especially in the services sector. The report is part of a broader FES-UNI Europa research project that is exploring the growing significance of AI-systems for European workers as well as prospects for collective bargaining to assert worker control over these new and proliferating tools.
