Abstract:
The Twin Transition is a cornerstone of EU policy, driving structural changes in European labour markets, yet a critical gap exists between policy and empirical evidence due to the lack of measurement instruments, a gap this study seeks to address. First, the results indicate that workers are likely to perceive the green and digital transitions as two distinct phenomena because of their differential tangible impacts, and so survey instruments should treat them as operationally separate to reduce cognitive burden and improve response validity. Second, some indicators used in the literature targeting company-level practices or perceived environmental impacts can lead to overestimation, in contrast to items based on factual, individual-level indicators grounded in workers' direct experience with their daily tasks. These should be complemented with more generalizable "soft" measures of synergies, whose reliability can be checked by segmenting responses by supervisory role. Finally, the study presents the questionnaire of the survey as a validated tool to measure the impact of the Twin Transition at the workplace.
