The transition towards a green economy, rapid development of digital technologies and demographic change are some of the forces disrupting traditional career paths, resulting in more fluid diversified career trajectories. To benefit from increased longevity, workers will increasingly have to consider job mobility at middle and older ages, changing jobs or careers more frequently than in the past. As in other countries, career mobility declines with age in the United Kingdom, yet voluntary mobility can provide opportunities to find better jobs, potentially improving job satisfaction, skills use and productivity. This report identifies key public and employer policies in the United Kingdom that can support career mobility at older ages. While the UK labour market remains dynamic providing ample job opportunities, not all workers benefit equally. Sustained public commitment to better-integrated career guidance, employment support and skills training is needed to support workers at all stages of their career. With workforce ageing, all stakeholders including employers must prioritise enhancing job quality along with health and well-being to prevent premature workforce exits. Key factors include fair pay, access to occupational health, supportive working conditions and workplace accommodation, flexible work options, and opportunities for ongoing learning and development.
