For three years, return-to-office mandates across the UK have arrived dressed in the language of productivity: collaboration suffers at home, junior staff miss out on mentorship, culture erodes on video calls. Research from the Wharton School at the University of Pennsylvania, co-authored by organisational psychologist Adam Grant with Marissa Shandell and Courtney Elliott, now suggests the real driver may be something far less flattering to the people signing those policies. Leader narcissism, the researchers find, is directly and significantly associated with resistance to remote and hybrid working.

For UK employees sitting on the receiving end of a mandate that does not seem to track their actual output, and for HR professionals fielding those decisions from the executive floor, this finding reframes the conversation. It is no longer purely about productivity data. It is about who is making the call, and why.

What the Wharton research actually says

The Wharton team examined whether business leaders with stronger narcissistic tendencies were more likely to resist remote and hybrid arrangements. They were, significantly so. According to the research and Adam Grant's accompanying commentary, leaders scoring higher on narcissism viewed distributed working as a threat to their power and status, rather than as a neutral operational choice. The researchers describe narcissism as the tendency to be self-centred and entitled, and argue that power is simply easier to perform in person.

That matters because, as Grant noted, much of the existing evidence on stricter return-to-office requirements shows limited or no measurable gains in worker output or organisational performance. If productivity is not improving, something else is motivating the mandates. The researchers point to personality.

There is a logic to it. Status display, walking the floor, having staff visible in glass-walled offices, calling impromptu meetings: all of this is harder to stage when half the team is at a kitchen table in another postcode. For a leader whose self-image depends on being seen as the centre of the operation, distributed work is not a flexibility question. It is an identity question.

In the UK context, this finding lands with particular weight. The Chartered Institute of Personnel and Development (CIPD), whose annual Good Work Index tracks the realities of UK working life for around 160,000 HR and people-management professionals, has consistently found that flexible working is among the most valued job attributes for employees across sectors. A policy framed as improving culture while quietly serving executive visibility needs runs directly counter to the employee trust that CIPD research identifies as foundational to engagement and retention.

For employees: what to do with this information

If you are on the receiving end of an RTO mandate that does not match your team's actual output, the Wharton finding gives you a sharper question to ask, both internally and in formal discussions: what business data is this policy responding to?

Under the Employment Rights Act 1996 (ERA 1996), employees in Great Britain with at least 26 weeks' continuous service have a statutory right to request flexible working, including hybrid or fully remote arrangements. Since April 2024, that right applies from day one of employment. Employers are required to consider requests reasonably and can only refuse on one of eight specified business grounds set out in ERA 1996 s.80G. A blanket RTO policy that cannot identify a qualifying business reason is, at minimum, difficult to defend against a well-framed flexible working request.

The Advisory, Conciliation and Arbitration Service (ACAS) publishes a statutory Code of Practice on handling flexible working requests. Where an employer refuses without engaging meaningfully with the Code, that conduct is relevant to any subsequent Employment Tribunal claim and may increase any compensation awarded.

A few practical steps worth considering:

• Ask for the metrics. When a mandate cites productivity or collaboration, request the underlying data. Reasonable organisations can share what they are measuring; defensiveness in response to that question is itself a signal worth noting.
• Document your own output. If you have hit targets, delivered projects, and maintained client relationships from home, record the specifics. Concrete evidence travels further than general impressions in any conversation about flexibility, and is essential if you decide to raise a formal flexible working request under ERA 1996 s.80F.
• Check the wider picture. Verified employee reviews and company culture data from platforms that collect anonymised, authenticated worker feedback can show whether the RTO push reflects a broader pattern across the organisation or is a one-off policy shift at a particular level of management.
• Know your alternatives. If the mandate is non-negotiable and the rationale remains vague, it is worth scanning the market. A number of UK employers have published public commitments to hybrid working, and ONS Labour Force Survey data consistently shows that hybrid roles attract a larger applicant pool than fully on-site equivalents in most professional occupations.

None of this requires accusing your CEO of narcissism, which would be both professionally unhelpful and unfalsifiable. It requires treating the policy the way any policy deserves to be treated: as something that should be backed by reasons you can examine.

For HR leaders: the harder conversation to have upstairs

HR teams are frequently asked to operationalise an RTO decision they did not make and were not consulted on. The Wharton research is useful here, not as a weapon against individual executives, but as a framework that lets you challenge a policy without making it personal.

There is also a legal dimension that belongs firmly in that executive conversation. Under the Equality Act 2010, a blanket requirement to attend the office five days a week may constitute indirect discrimination against protected groups, including disabled employees, those with caring responsibilities disproportionately affecting women, and others for whom remote working serves as a reasonable adjustment. ACAS guidance on indirect discrimination makes clear that policies neutral on their face can still be unlawful if their practical effect falls harder on a particular group and the employer cannot objectively justify the provision, criterion or practice. A policy backed only by executive preference, rather than a demonstrable business aim, fails that justification test.

A few angles worth raising in the next executive conversation:

• Separate the business case from the personal preference. If senior leadership wants people back, ask what business outcome the mandate is meant to improve and how it will be measured at six and twelve months. The Wharton finding is a reminder that it simply feeling right is not a measurable outcome and, in an Employment Tribunal context, is not a defence.
• Look at retention exposure. Blanket RTO policies tend to lose the people with the most external options first: mid-career specialists, working parents, and high performers who can negotiate quietly elsewhere. Your attrition data over the twelve months following a mandate will be more instructive than any engagement survey. For UK employers, this is particularly acute given that CIPD's Resourcing and Talent Planning Survey identifies flexible working as a primary lever in attracting hard-to-fill roles.
• Audit the visibility bias. If promotions, stretch projects, and informal developmental feedback flow disproportionately to people physically present in the office, the organisation has built a structural disadvantage for hybrid workers. Where that disadvantage correlates with a protected characteristic, it may constitute indirect discrimination under the Equality Act 2010 s.19. Identifying and correcting that pattern is a design problem; addressing it requires looking for it deliberately.
• Protect the policy from a single voice. Decisions grounded in output, retention, and recruitment data survive leadership changes. Those resting on one executive's preference do not. A data-backed policy is also easier to defend if a flexible working refusal reaches Employment Tribunal, easier to communicate to staff, and easier to adapt when business conditions shift. The union Prospect, which represents engineers and professional workers across UK employers including ARM Holdings and others in the technology and advanced manufacturing sectors, has flagged RTO mandates as a live bargaining issue in a number of recent recognition agreements.

The Wharton paper does not say every RTO mandate is driven by a narcissistic leader. It says narcissism was the trait that consistently predicted opposition to remote working, even when the business case for that opposition was thin. That is a useful diagnostic, not a verdict, and it is the kind of framing that an HR director can bring to a board-level conversation without it reading as a personal attack.

Why the framing shift matters for UK workplaces

For most of the post-pandemic period, the debate about office attendance has been waged on the terrain of productivity: a terrain where the evidence is genuinely mixed, frequently contested, and easy to cherry-pick in either direction. The Wharton research opens a second front, centred on the psychology of the people making the decision rather than the output of the people affected by it.

That shift is uncomfortable, and rightly so. Workplace policy is not supposed to function as a staging ground for executive self-image. When it does, the costs are measurable: higher attrition among mobile workers, legal exposure under the Equality Act 2010 and ERA 1996, and the kind of trust deficit that the CIPD's Good Work Index consistently identifies as a predictor of disengagement. Three years of mandates whose stated rationale has not matched their measurable results is long enough to warrant a harder look at the motivation behind them.

The High Pay Centre, which tracks executive pay and governance in UK-listed companies, has previously noted that board-level accountability for workforce decisions, including attendance policy, remains patchy relative to accountability for financial performance. Where a CEO's preference for visible control shapes a major employment policy, that is a governance question as much as an HR one, and it sits squarely within the scope of what ACAS describes as the reasonable employer standard in managing employment relations.

For employees, the practical takeaway is permission to ask better, more specific questions of the policies that govern their working lives. For HR leaders, it is permission to push back on decisions that arrive without a business case: armed now with an independent body of research that frames the issue in strategic rather than confrontational terms. Either way, the conversation about where people work in the UK has finally started to catch up with the more difficult conversation about why.
