Workplace wellbeing: why investment is not reducing absence or improving performance

Organisations can invest heavily in workplace wellbeing and still see high absence, pressure and declining performance. The reason is often that wellbeing initiatives address the symptoms while factors such as workload, leadership, culture and the way work is designed remain unchanged.

Average sickness absence in the UK now stands at 9.4 days per employee per year, up from 5.8 days before the pandemic and 7.8 days in the 2023 report, the highest level in at least 15 years (CIPD, 2025). Within the same survey data, work was reported as a contributing factor in 62% of anxiety cases and 53% of depression cases (CIPD, 2025).

What makes those figures worth sitting with, is that they arrived during a period in which organisational investment in employee wellbeing rose consistently and visibly. More organisations have standalone wellbeing strategies than at any point on record, more senior leaders have wellbeing on their formal agendas, and the range of provision on offer has expanded significantly. The investment did not prevent the trend, and that tension between rising commitment and worsening outcomes is the starting point for any serious conversation about what workplace mental health provision is doing.

That conversation feels more pressing now than it might have done in a more settled period. The conditions that drive psychological harm at work do not ease under pressure, they build, and organisations operating through sustained uncertainty are not working from a neutral baseline. The gaps in provision that were manageable in calmer times tend to become costly precisely when the organisation can least afford them.

While 64% of organisations say they are actively trying to tackle workplace stress, only half believe those efforts are actually making a difference (CIPD, 2025). That suggests the issue isn’t a lack of intent, but how those efforts are designed. In a more uncertain and demanding environment, that mismatch becomes much harder, and far more costly, to ignore.

The source, not the symptom

A quarter of UK workers (an estimated 8.5 million people) say that work has a negative impact on their mental health. When the CIPD examined what most strongly predicts that outcome, the answers were consistent: excessive workload, excessive pressure, poor relationships with colleagues, and the quality of direct line management (CIPD Good Work Index, 2025). Not inadequate EAP provision, not insufficient awareness activity. The structural conditions of how work is organised and led.

Organisations that invest in training line managers to support staff experiencing mental ill health see the difference clearly. Those managers feel equipped to have the conversations that matter, they have them earlier, and the results show up in absence figures, in engagement scores, and in retention. The underlying difficulty gets addressed rather than quietly accumulating until it appears in an exit interview or a long-term absence notification.

Culture is shaped by leadership behaviour far more decisively than by any wellbeing initiative, which means it is also, for any organisation serious about absence reduction, the most important intervention available. The investment question worth asking is whether the organisation is genuinely building the leadership capability that produces that kind of culture, or funding provision that treats the symptoms leadership behaviour generates while leaving their source intact.

The diagnostic step most organisations skip

The organisations that see the greatest returns from mental health investment tend to share one characteristic: they treat this as a problem to be diagnosed before it is a problem to be solved, applying the same rigour they would bring to any other significant business risk.

A proper diagnostic maps workforce experience against workload, leadership behaviour, team relationships, and what the existing support structures are and are not doing. It produces an evidence base specific to that organisation rather than a framework applied from outside, and the interventions that follow work at a higher rate because they are addressing identified causes rather than presenting symptoms.

The CIPD is direct on why most organisations do not get here: the dominant mode of wellbeing activity in UK workplaces remains reactive rather than proactive, with interventions commissioned in response to symptoms rather than causes (CIPD, 2025). Resilience training follows a period of elevated stress. EAP upgrades follow an absence spike. The cause that produced both continues to operate largely undisturbed.

Deloitte's analysis suggests that employers see a return of approximately £4.70 for every £1 invested in employee mental-health support (Deloitte, 2024). The size of that return does not come from the scale of the programme alone. It depends on whether the investment was targeted at the cause, and organisations that get that right tend to find they are building something more durable than a wellbeing programme, they are building a healthier culture.

What qualified clinical provision can surface

When employees engage with a qualified clinical practitioner in a completely confidential setting, they sometimes disclose difficulties, or recognise them for the first time, that have been quietly shaping their performance for years without anyone identifying why. A clinical psychologist or psychotherapist brings training that a helpline, a digital platform, or a mental health first aider is not designed to replicate: specifically, the ability to hear what is not being said alongside what is, and to recognise a clinical presentation when it emerges.

The early identification of a need that would otherwise surface later, in a more acute form and at considerably greater cost, is what distinguishes this level of provision from reactive support. An employee whose unrecognised difficulty is identified and properly addressed represents a retention outcome, a performance outcome, and a risk outcome simultaneously.

The return on rigour

The cost of workplace mental ill health continues to rise, and so does the investment intended to address it, with no credible sign of either reversing and nothing in the current environment to suggest that is about to change.

The provision most organisations have adopted is not working in the way the problem demands. Awareness campaigns, digital platforms, and employee assistance programmes are easy to procure and easy to report on however they are becoming increasingly harder to justify when set against three years of worsening absence data.

The alternative of diagnostic-led, clinically grounded intervention, is more demanding to design and deliver. Defaulting to what is easier to procure and easier to explain is a logic many organisations will recognise.

It makes sense until you look at the absence data, then it just looks expensive.
