4 Day Week Brazil: Analisando a Viabilidade de Longo Prazo da Jornada Reduzida de Trabalho

This final PIBIC report presents the longitudinal study of the 4 Day Week Brazil pilot, examining the long-term viability and impacts of reduced working time after the end of institutional implementation support. The research adopted a qualitative-quantitative approach, with qualitative predominance. Fourteen synchronous online interviews and one asynchronous
interview by email provided longitudinal information on 15 of the 17 organizations that completed the pilot. The analysis compared the post-pilot situation with the third round of data collection, organized the cases in an audited comparative matrix, identified recurring patterns, and triangulated the findings with the previous PIBIC study, the official 4 Day Week Brazil
report, and the academic literature. The trajectories included full, adapted and partial continuation, replacement by other forms of flexibility, and discontinuation. The findings indicate that long-term sustainability depends on the capacity to protect non-work time, redistribute responsibilities, create coverage, monitor workload and deliveries, integrate new employees, and renegotiate rules when organizational or external conditions change.
