The deep and rapid changes in the world of work driven by the digital and green transformations as well as population ageing have been associated with greater job instability, with potential costs for companies, workers and society. The unprecedented labour and skill shortages that emerged during the recovery from the COVID-19 pandemic have raised further the importance of developing and retaining talent. In the context of a more age-diverse workforce, addressing this challenge will require better working conditions, greater investments in training and tackling difficulties in reconciling work with health issues and caring responsibilities. This report presents evidence on recent trends in job tenure and employee turnover, how they have changed due to the COVID-19 shock and sheds light on why employees quit their jobs. It identifies key employer and public policies that can support increased employment retention through better job quality, health at the workplace, and training and skills.
