When Work Schedules Decide Who Can Care
This series examines a concrete policy question: how did the United Kingdom’s 2014 expansion of the Right to Request Flexible Work change who provides unpaid adult care? The opening focus is the connection that is easy to miss. Care is a changing supply of time, attention, and practical work, while paid employment is organised through schedules, locations, and expectations about availability. Understanding that connection gives the reader a way to judge the evidence that follows: distinguish more people providing care from the same people providing more care, and distinguish control over working time from simply working fewer hours.
Adult care is a moving supply, not a fixed role
When an older person becomes frail, a partner develops a long-term health condition, or an adult child needs support because of disability, the question is not only whether care is needed. It is also who will provide which parts of it, at what times, and for how long. Some help is visible: bathing, dressing, lifting, preparing meals, or accompanying someone to an appointment. Other work is easier to overlook: arranging paid care, managing benefits and finances, collecting prescriptions, checking in by phone, or making sure that a care plan is followed. In this series, adult informal care means unpaid support for adults with care needs, not childcare. It may take place inside the carer’s household or somewhere else, and it can range from occasional help to care that occupies most of a working week.
The scale makes this more than a private family matter. The OECD reports that, across 19 OECD countries, about 60% of older people who received care reported receiving only informal care. Across the countries included in one of its indicators, more than one in eight people aged 50 and over provided informal care, and 61% of informal carers were women. These figures are useful for showing the role of families and social networks in long-term care, but they are not a single universal measure: the surveys use different definitions of care, age groups, and questions about frequency.
The UK figures show both scale and movement. The Department for Work and Pensions reports that 5.4 million people, or 8% of the UK population, provided some unpaid care in 2023/24. That total included 3.3 million women and 2.1 million men. Yet the caring population is not a permanent category into which people enter once and never leave. Between 2010 and 2020, an average of 4.3 million people took on new unpaid caring roles each year while 4 million stopped. People can become carers when needs emerge, reduce their involvement when arrangements change, resume care after a period away, or share tasks with others without ever adopting the label.
That movement changes what “who provides care” should mean. One question concerns the extensive margin: does a person provide any care at all? Another concerns the intensive margin: how many hours or how much responsibility does that person take on? Location matters too. A person who begins helping a parent in the same household is making a different adjustment from someone who adds occasional visits or organises services from a distance. A policy can affect one of these margins without changing the others. It can bring another family member into the network, reduce the most demanding share carried by an existing carer, or make a previously unstable arrangement possible while leaving the total amount of paid work almost unchanged.
The gender pattern makes these distinctions essential. Women provide a larger share of unpaid care in the descriptive data, but that does not tell us how men and women face the same care need. A conventional full-time schedule may be especially difficult for a man who has not previously been expected to take a regular care role, while a woman may already be carrying a large share of the work and be more likely to adjust by reducing hours or limiting career opportunities. The relevant policy question is therefore not whether one gender is naturally more caring. It is whether working conditions change the constraints that make particular forms of care more or less feasible for different people.
The hidden variable is the timing of work
Paid work and unpaid care compete for more than a total number of hours. They compete for particular moments. A hospital appointment may occur during the working day. A person with dementia may need supervision at irregular times. A paid-care service may arrive late, cancel, or cover only part of the day. A worker may be able to perform the same number of paid hours and still be unable to provide care if those hours are fixed in the wrong places.
This is why flexible work can matter even when it does not look like a reduction in labour supply. Changing a start or finish time, moving some work away from a fixed location, compressing hours, or sharing a job can loosen the conflict between a work schedule and a care task. The change may lower the cost of being available at a particular moment rather than lower the total amount of paid work. It may also make it possible to respond to an emergency without immediately abandoning the job that supplies income, social contact, and professional identity.
The practical outcome depends on the care network around the worker. Suppose two siblings live in different places and one of them has the only job that can be rearranged at short notice. Under a rigid schedule, that sibling may be unable to help even if they are willing; the other sibling may gradually become the default carer simply because they live closer or have more control over their day. If the first sibling gains usable control over working time, the family may be able to share appointments, supervision, or administrative work more evenly. The same change could instead allow one person to take on additional care that no one else can provide. Flexibility changes the feasible allocation; it does not dictate the allocation by itself.
Nor is the informal network the whole system. Local-authority support, paid home care, day services, respite, assistive technology, and help with ordinary household tasks can alter how much unpaid care a family needs to supply. Financial resources and geography determine whether those alternatives are real rather than merely listed on a website. An employer’s willingness to discuss a schedule also matters. A formal right that exists on paper but is difficult to use in a particular occupation, or a workplace where disclosure is treated as a sign of weak commitment, may not relieve the binding constraint.
The possible effects therefore run in more than one direction. More control over working time may enable a man to take on a regular share of care that he previously could not fit around work. It may help an existing female carer step back from the most intensive tasks when another family member becomes involved. It may preserve employment while a family absorbs a temporary shock. But it can also make it easier for a worker to absorb more unpaid care without receiving additional formal support. A flexible schedule can reduce the conflict between roles while leaving the underlying volume of care, uncertainty, and emotional responsibility intact.
The diagram’s central point is modest but important. Flexible work is one input into a network that also contains care needs, family relationships, paid services, and workplace conditions. Its most direct contribution is to alter the worker’s available timing and control. The resulting change in care is a household and institutional outcome, not a guaranteed consequence of receiving a legal entitlement.
The question is narrower than “does flexibility help?”
The policy examined in this series is the UK’s 2014 expansion of the Right to Request Flexible Work. Before the reform, the statutory right was limited to particular groups. From 30 June 2014, an employee with at least 26 weeks of continuous service could formally request flexible working, including changes involving hours, schedules, or location. The reform extended the right to employees dealing with adult-care needs, but it did not promise that every request would be approved or that every job could support the same arrangement. That distinction between eligibility, workplace availability, employee use, and actual care consequences will matter throughout the evidence.
Three kinds of source help answer different parts of the problem. The OECD provides a broad view of how much long-term care is supplied informally, who supplies it, and why ageing societies may face pressure on that supply. The DWP’s research follows people making early decisions about work and care, showing how family expectations, fragmented information, employer culture, and the timing of support can narrow their perceived options. The IZA study provides the direct policy test: it compares employees who lacked access to flexible arrangements before the reform with employees who already had access, using longitudinal UK data to estimate changes in care and mental health.
These sources should not be blended into one level of certainty. A cross-national percentage does not measure the effect of the UK reform. A qualitative account of a family’s decision journey does not prove that a particular information intervention will keep people employed. A difference-in-differences estimate can be more informative about the reform’s effect than a simple correlation, but it still depends on its comparison and measurement assumptions. Keeping those roles separate prevents two opposite mistakes: treating flexible work as a universal cure, or dismissing a meaningful change because it does not solve every part of the care system.
The central question is consequently precise: when a work constraint is relaxed, which care margin changes, for whom, and through what relationship between the worker, the household, and formal support? The answer may involve more participation by one group, less extreme intensity for another, and little change in total paid hours. It may also depend on whether people already have a connection to caregiving and whether the workplace makes the nominal right usable.
The next step is to examine what the 2014 right actually changed and how researchers identified its effects. That policy detail is not a detour from the care question. It is what allows us to tell the difference between a legal reform that changes the conditions of work and a broader story about people who were already more able—or more likely—to provide care.
