More than three million people in the UK are now claiming long-term sickness benefits, and this film asks why that number keeps climbing. Reporters and interviewees examine the strain on the welfare system, tracking how claims for conditions ranging from mental health struggles to chronic pain have swelled well beyond pre-pandemic levels. The film sets out the competing explanations on offer: a genuine rise in ill health, a benefits system that makes it easier to claim than to return to work, and a labor market that has left some people permanently sidelined. Officials, claimants, and policy analysts weigh in on what the surge means for public spending and for the people caught inside a system many describe as slow and adversarial. The film treats the crisis as both a fiscal problem and a human one, following the paperwork and the waiting lists as closely as the political argument over what, if anything, should change.
