Why long COVID and mental-health claims are reshaping pay protection for modern workers

Pay protection is changing because the health risks affecting workers have changed too. Where older benefit designs were often built around a clear injury, a short illness, and a fairly predictable return-to-work timeline, modern claims are increasingly shaped by long COVID, burnout, anxiety, depression, and other conditions that can fluctuate from week to week. For UK households trying to understand how income protection fits into real life, this matters because the gap between being unwell and being financially secure can open up very quickly.

Recent evidence helps explain why this shift is so important. CIPD reported in 2025 that average UK employee absence reached 7.9 days per employee, still well above the 5.8 days seen before COVID-19. The same coverage also noted that a quarter of employees believe work is harming both their mental and physical health, equivalent to around 8 million people across the UK workforce. In other words, conversations about sick pay and income protection are no longer niche HR issues; they are now central to family financial planning.

Long COVID has turned short-term sickness assumptions upside down

One reason pay protection is being reshaped is that long COVID does not fit neatly into traditional rules. Many older sick-pay systems were designed around illnesses that either resolved relatively quickly or developed into more clearly defined long-term disability. Long COVID sits awkwardly in the middle: symptoms can last for months, vary in severity, and affect concentration, stamina, breathing, and day-to-day functioning in ways that are hard to predict.

That uncertainty is not theoretical. CDC materials presented in June 2025 said 3.6% of U.S. adults reported current long COVID, and more than 3 in 5 adults with long COVID reported activity limitations. While this is U.S. data, it reinforces a wider point for UK readers: post-viral illness remains a live workforce issue, and employers, insurers, and policymakers are still grappling with how to support people whose ability to work may be reduced without being uniformly absent every day.

The U.S. Department of Labor’s rapid review on long COVID also highlighted prolonged functional limitations affecting work, adding weight to the idea that benefit systems need more flexibility. In practice, that means modern pay protection increasingly has to account for phased returns, partial capacity, stop-start recovery patterns, and periods where someone may be able to work some days but not others. For workers, that makes understanding the fine print of sick pay and income protection far more important than it used to be.

Mental health claims are now central, not secondary

The other major force reshaping pay protection is mental health. Historically, many workplace benefit systems treated psychological conditions as harder to validate, less severe, or more limited in duration than physical illnesses. That approach now looks increasingly out of step with the reality of modern absence patterns.

The UK Civil Service’s 2025 sickness report found that mental ill health was the largest cause of long-term sickness absence at 47.1%, while long-term sickness days per staff year rose to 4.9 days. That is a significant signal because it shows mental health is not a side issue in workforce absence; it is one of the biggest drivers of prolonged time away from work. When long-term absence is increasingly linked to anxiety, depression, trauma, stress, or cognitive strain, pay-protection models built mainly around visible physical conditions become less suitable.

CIPD’s wider findings point in the same direction. Its 2025 materials said organisations remain more reactive than preventive on health, while earlier survey findings showed 76% of employers reported some stress-related absence and 69% offered occupational sick pay. Together, these figures suggest a workplace landscape where mental-health-related absence is common, support expectations are rising, and employers are under pressure to provide better pathways for recovery without pushing people into financial hardship.

Why statutory sick pay often falls short for prolonged recovery

For many workers, the biggest practical problem is simple: statutory sick pay is often not enough when recovery is long, uneven, or linked to recurring symptoms. If someone is dealing with fatigue, brain fog, anxiety, or depression over many months, a basic minimum payment may provide only limited financial resilience.

UNISON noted that for 2025/26, UK Statutory Sick Pay is £118.75 per week, paid from the fourth day of sickness for up to 28 weeks, with expected reforms from April 2026 moving SSP to the first day of sickness. While any improvement helps, the current level remains modest compared with normal household bills, mortgage payments, rent, childcare, and transport costs. That means the real financial burden of illness often shifts quickly onto savings, partners, debt, or employer-enhanced support.

This is why employer sick pay and private income protection are becoming more consequential. The old assumption that statutory support could bridge a relatively short illness is less convincing when conditions are chronic, relapsing, or mentally exhausting rather than clearly acute. Workers increasingly need to know not just whether they have sick pay, but how long it lasts, what percentage of income it replaces, whether mental health is treated fairly, and what happens if they can only return part-time.

Accommodation and flexibility are now part of pay protection

Pay protection is no longer only about what happens when someone stops working completely. It is also about whether they can stay connected to work safely enough to avoid a complete loss of income. That is one reason long COVID has had such a strong effect on employer thinking: it has highlighted the value of practical adjustments alongside wage support.

The U.S. Equal Employment Opportunity Commission says long COVID can qualify as a disability under the ADA when it substantially limits a major life activity, and it lists accommodations including telework, flexible schedules, rest breaks, reduced exertion, quieter workspaces, and modified lighting. Although this is U.S. disability guidance, the broader principle is highly relevant in the UK too. Flexible work arrangements can reduce the gap between total absence and productive work, especially for workers with fatigue, concentration problems, breathlessness, or sensory sensitivity.

For employees and families, this broadens the meaning of financial protection. A worker may not need full income replacement if the employer can support a phased or adjusted return that preserves earnings. But without those adjustments, the same person may face a much sharper income drop. In that sense, modern pay protection increasingly sits at the intersection of sick pay, workplace adjustments, return-to-work planning, and good line-management practice.

Legal and regulatory pressure is pushing toward parity

Another reason this area is changing is that legal and regulatory debates are moving toward parity. Put simply, workers increasingly expect behavioural, cognitive, and post-viral conditions to be treated more like physical illnesses and injuries. That expectation is visible across disability guidance, benefit reform discussions, and disputes about whether older plan designs discriminate against modern health realities.

In the U.S., the proposed Workers’ Disability Benefits Parity Act of 2025 would amend ERISA to address unequal treatment of behavioural-health versus physical-health disabilities in long-term disability plans. That proposal drew on a 2023 Labor Department advisory report, which concluded that mental-health limits in long-term disability coverage are a real disparity problem. Even though these are U.S. developments, they matter internationally because they reflect a broader policy direction: the idea that mental-health-related incapacity should not automatically be treated as less worthy of wage protection.

At the same time, mental-health parity rules for employer health coverage were strengthened in 2024, with CMS saying the final rule was designed to improve access for more than 150 million people with private health coverage. Yet in May 2025, the U.S. Departments of Labor, HHS, and Treasury said they would not enforce that 2024 final rule while litigation continues. For employers, that kind of regulatory uncertainty is itself part of the story. Compliance rules may shift, but workforce expectations do not disappear, so organisations still face pressure to support mental-health claims in a fair and practical way.

Tribunals, disputes, and politics show the stakes are rising

Long COVID and mental health are not only changing benefits quietly in the background. They are also becoming legal, industrial, and political flashpoints. That matters because once disputes move into tribunals, public campaigns, and policy battles, employers tend to review their approaches more seriously.

Analysis reported in February 2025 found 164 UK employment tribunal claims involved workers with long COVID in 2024, up from 144 in 2023 and 88 in 2022. This trend suggests that long COVID is increasingly moving beyond absence management into legal risk, disability arguments, and disagreements over support, pay, and workplace adjustments. For employers, better-designed pay protection can be part of preventing those disputes from escalating.

International examples underline how politically sensitive this can become. Ireland confirmed in April 2025 that its special long-COVID sick-pay scheme for public health workers would be wound down, illustrating how governments are reassessing whether pandemic-era protections should continue. The backlash was intense: in November 2025, Irish Labour said 159 healthcare workers with long COVID would lose access to full pay as the special scheme ended. A 2025 BMJ report also said unions were calling it unconscionable that long COVID had not been recognised as an occupational disease for health and social care staff, citing estimates that up to 4.41% of healthcare workers had acquired long COVID.

Income protection design is shifting toward realism

As these pressures build, benefit design is moving slowly toward more realistic wage replacement. A useful illustration comes from California, which announced that in 2025 disability and paid family leave benefits would rise to as much as 90% of pay for workers earning under $63,000, and 70% for higher earners. While this is not a UK policy, it shows one practical response to modern illness and caregiving risk: if recovery periods are longer and family finances are tighter, higher replacement rates may be needed to make support genuinely useful.

There is also growing recognition that income protection can influence recovery behaviour. A 2024 NHS CHECK study found widespread COVID-related sickness absence among healthcare workers and noted that ending special sickness payments in September 2022 may have pushed some staff to return before they were ready, rather than face reduced pay or possible job loss. That is an important lesson. Poorly designed pay protection does not simply save money; it can create pressure for premature returns, which may worsen health outcomes and complicate workforce planning.

For UK workers, the takeaway is practical rather than theoretical. When reviewing workplace benefits or considering personal income protection, it is worth looking for features that reflect real life: meaningful benefit levels, suitable deferred periods, support for phased returns, fair treatment of mental-health-related claims, and definitions of incapacity that recognise fluctuating conditions. The strongest policies are increasingly the ones built for uncertainty, not just for short, straightforward illnesses.

The bigger picture is that pay protection is being reshaped because modern illness is reshaping work itself. Long COVID has exposed the limits of systems designed around simple absence and recovery patterns, while mental-health-related claims have challenged assumptions that only physical conditions deserve robust wage protection. As evidence from employers, governments, regulators, and researchers continues to build, the direction of travel is clear: flexibility, parity, and realistic income replacement are becoming more important.

For UK households, this does not mean every worker needs the same solution. But it does mean understanding sick pay, employer benefits, and income protection is now a core part of financial resilience. A no-pressure review of what support is available, how long it lasts, and where the gaps may be can help families plan with more confidence, especially in a world where recovery is not always quick, linear, or easy to predict.
