A new report from the Royal Society of Public Health (RSPH) reveals that the UK could lose an additional 6,00,000 workers over the next decade due to long-term health conditions. This growing trend is expected to cost the UK economy a staggering £36 billion annually.
According to the analysis, by 2035, more than 3.3 million adults are projected to become economically inactive because of conditions such as musculoskeletal disorders, mental health issues, and cardiovascular diseases.
The report highlights a 26 per cent increase in workforce inactivity, which is the equivalent of the entire population of Bristol leaving the workforce. This sharp rise underscores the pressing need for a fundamental shift in how employers address employee wellbeing and health support, particularly in the face of an ongoing productivity crisis. Many of these health issues, if left unaddressed, could lead to prolonged economic inactivity, further straining the nation’s economic output.
The findings come as the government prepares to release the Keep Britain Working review, which is set to propose recommendations aimed at reducing health-related inactivity in the workforce.
Previous RSPH studies have shown that nearly half of UK workers do not have access to basic health support at work, such as flu vaccinations or cardiovascular checks. This lack of support leaves many employees vulnerable to health issues that could lead to long-term absences and, ultimately, early retirement due to health conditions. The gap in workplace health provisions contributes directly to the rising number of people becoming economically inactive.
However, the report suggests that the key to mitigating this challenge is ensuring that workers remain healthy and in work for as long as possible. Proposals include establishing clearer standards for workplace health and expanding access to specialist “caseworker” support, which could help employees manage chronic conditions while continuing their employment. Additionally, encouraging employers to invest in health initiatives, especially for line managers, can reduce turnover, cut down on presenteeism, and boost productivity.
Furthermore, the report highlights the importance of “good work” for both individual health and the wider economy. As part of its 10-year health plan, the government is shifting focus from a reactive sickness model to a preventive approach, aiming to provide personalised support to workers and encourage employers to do the same.
As long-term health conditions continue to affect millions of workers, the UK must take concrete steps to keep people in the workforce, enabling them to contribute to the economy and creating a healthier, more prosperous future for all.
