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. Across the OECD, the average length of a job held by the same worker declined by around nine months between 2012 and 2019, and the decline has been felt across all age groups. This fall in job stability coincides with people changing jobs at a fast pace, sometimes at the highest rate seen in recent decades – one in five workers experience a change in their employment situation every year – and the rate of job change has increased in 24 out of 27 OECD countries for which data are available over time. Older people aged 55‑64 do not switch jobs seamlessly – whether they quit or lose their job – they will often end up unemployed or will leave the labour market. Once out of work, they are far less likely to find a new job and more susceptible to large wage cuts upon hiring.
