The RTO debate is, for the most part, over. The office won.

As of mid-2026, 54% of Fortune 100 employees are subject to five-day office requirements, up from just 11% a year prior, according to JLL's Q2 2025 Office Market Dynamics report. Amazon, JPMorgan Chase, Goldman Sachs, AT&T, and Dell are among the major employers requiring full-time in-person attendance. The share of companies offering fully remote roles has collapsed from 21% to just 7%.

And resistance has faded. In January 2025, 51% of employees said they would quit rather than comply with a mandatory RTO policy. By early 2026, that figure had dropped to 7%. Researchers are calling it the Great Compliance.

But compliance is not engagement. And presence is not productivity.

The office has won the attendance battle. It now faces a much harder one: justifying why people are there.

The Compliance Trap

The data behind the Great Compliance is less triumphant than it appears. Eight in ten companies report losing talent as a direct result of their RTO policies. Organisations with strict mandates have turnover rates approximately 13% higher than those with more flexible setups. And 41% of employees subject to five-day mandates say they are actively job hunting.

People are showing up. But many are showing up while looking for a way out.

This is the compliance trap: mandating presence without redesigning purpose.

When the office offers the same experience, it did in 2019 rows of desks, endless meetings, and employees spending most of the day on laptops and video calls; attendance becomes performance rather than value creation.

This is not merely an employee grievance. Writing in Harvard Business Review (July–August 2025), Wharton professor Peter Cappelli and senior HR strategist Ranya Nehmeh argued that hybrid arrangements hurt collaboration, exacerbate social isolation, and weaken culture; making a clear evidence-based case that physical presence does matter. But their conclusion was equally clear: the answer is not simply mandating attendance. It is designing the office so that being there actually delivers on those benefits. Presence without purpose achieves neither.

A Note for UK Leaders: The Legal Landscape Is Different

Much of the RTO conversation is framed around US employers, where mandates can be issued with relatively few legal constraints. The picture in the UK is meaningfully different, and it matters for any organisation with a London presence.

Since April 2024, the Employment Relations (Flexible Working) Act gives UK employees the right to request flexible working from Day 1 of employment, removing the previous 26-week qualifying period. Employers are legally required to consult before rejecting any request and must respond within two months. Employees can make two requests per 12-month period.

This doesn't prevent UK employers from setting expectations around in-office attendance. But it does mean that blanket five-day mandates issued without consultation carry legal risk, and that the cultural approach to RTO in London cannot simply mirror what's happening in New York or San Francisco. UK talent leaders need a policy that is both legally defensible and genuinely purposeful.

AI Has Changed What the Office Is For

The original case for the office was coordination: shared information, aligned decisions, real-time collaboration. Those functions made physical proximity genuinely valuable.

AI is dismantling that case. According to ActivTrak's 2026 State of the Workplace report, 80% of employees now use AI tools at work, up from 53% two years ago. Tasks that once required a meeting room, transcription, scheduling, project updates, status reporting, document drafting, are increasingly automated. Gartner predicts that by end of 2026, 40% of enterprise applications will feature task-specific AI agents, up from less than 5% in 2025.

The coordination layer of work is being absorbed by AI. Which leaves the office needing to answer a harder question: what does it offer that AI cannot?

Microsoft's 2026 Work Trend Index, which analysed trillions of Microsoft 365 productivity signals and surveyed 200,000 workers globally, put it bluntly: AI access is no longer the advantage. Work design is. 58% of workers say AI has allowed them to produce better quality work than a year ago. Two-thirds say it has freed up time for higher-value activity. But the organisations seeing the greatest gains are those that redesigned workflows around AI, not those that simply handed out tool licences.

Case study: Salesforce

Salesforce deployed its Agentforce AI platform internally and used autonomous agents to handle 3 million customer support conversations. Year-on-year support caseload dropped 8%, more than 170,000 fewer cases, while the company cut $100 million in support costs. Crucially, Salesforce then published a public blueprint for how to build a collaborative AI-human workplace, framing agents not as headcount replacements but as a new layer of the workforce that humans direct and oversee. (Fortune, April 2026)

Presence without redesign is the most expensive mistake a company can make in 2026.

The AI Paradox: Heavy Users Want More Office Time

Not all the data points toward obsolescence. Gensler's 2026 Global Workplace Survey found something counterintuitive: the most frequent AI users are also the workers who most value in-person collaboration.

AI power users spend less time working alone, 37% of their workweek versus 42% for non-power users, and more time learning (12% vs 8%) and socialising with colleagues (11% vs 9%). They report wanting more time in the office, not less, provided the space supports how they actually work.

This suggests the office isn't dying. It's specialising. The question is whether organisations are moving fast enough to meet that shift.

The Generational Fault Line

Layered beneath the RTO debate is a generational tension that very few organisations are addressing openly.

Gen Z, now the fastest-growing segment of the workforce, has grown up with AI as a native tool. According to Deloitte's 2026 Global Gen Z and Millennial Survey, 74% of Gen Z workers report using AI in their day-to-day work. Many say they are adapting to it faster than their organisations. 40% say they can no longer get by without it.

Their relationship with AI is complex, though. Research published in Harvard Business Review in January 2026 by psychologist Angela Duckworth and colleagues at the University of Pennsylvania found that Gen Z workers simultaneously believe AI is critical to their own advancement while worrying it is making their colleagues less capable. 79% expressed concern that AI makes people lazier. 62% worried it makes people less smart. Many admitted to using it as a crutch, yet few would give it up.

Meanwhile, many of the executives enforcing five-day mandates built their professional identities in office cultures that predate both remote work and AI. The result is a leadership layer that is optimising for a model of work that the people entering the workforce have never known, and don't necessarily want.

This is not an argument for abandoning structure. It is an argument for making sure the structure you enforce has a clear purpose that the next generation of talent can actually see.

What Forward-Thinking Organisations Are Actually Doing

The organisations navigating this well are not asking "how do we get people back?" They're asking "what does the office need to become?"

Collaboration by design, not default. Office days are structured around activities that require physical presence, workshops, decision-making sessions, onboarding, mentorship, cross-team problem-solving, rather than replicating remote desk work in a shared space.

AI-augmented environments. Smart meeting rooms that auto-summarise and assign actions, AI-powered space management, and ambient tools that reduce administrative overhead, so that in-person time is spent on high-value interaction, not logistics.

Culture as infrastructure. Gartner's May 2026 research warns that 50% of enterprises without a people-centric AI strategy will lose their top AI talent by 2027. The office is increasingly where culture, values, trust, belonging, is built and maintained. That cannot be automated. But it also cannot happen passively.

Measuring outcomes, not attendance. The most sophisticated employers have moved away from badge-swipe metrics toward output-based performance frameworks. 69% of employers now measure attendance, but the leading edge is measuring what people actually produce during that time.

The Talent Implications

For HR and talent leaders, the implications are direct. The organisations winning the talent competition in 2026 are not those with the most flexible policies or the most rigid mandates. They are the ones with the clearest answer to the question every candidate is silently asking:

Why does being in your office make my work better?

Companies that cannot answer that question will continue to see the talent drain that RTO mandates have already triggered. Companies that can answer it, that have redesigned their spaces, workflows, and cultures around what humans uniquely offer; will find that the office becomes a genuine competitive advantage rather than a contested obligation.

The Bottom Line

The age of AI has not made the office irrelevant. It has made the old office irrelevant. The difference matters enormously.

Coordination, information transfer, and routine collaboration are being automated. What remains, and what the office must now be built around is everything AI cannot replicate: trust, creativity, mentorship, culture, and the kind of thinking that only happens when the right people are in the same room with the right conditions.

The office is full again. The organisations that will pull ahead are the ones that make sure it's full for the right reasons.
