The Iran War is reshaping the working week. Is your office ready?

Several Asian governments have moved to four-day work weeks as an emergency fuel measure. The last time a global crisis forced a shift in how people worked, the change proved lasting. This article explores what is happening, what experts think it means, and what questions workplace leaders are worth asking right now.

1. What is happening right now

On 28 February 2026, US and Israeli forces launched strikes on Iran. Within days, Iran closed the Strait of Hormuz to maritime traffic. The Strait is the single waterway through which approximately 20% of global oil normally passes.[1] The International Energy Agency described the resulting disruption as “the greatest global energy security challenge in history.”[2]

Brent crude, which traded below $70 per barrel before the war began, surged past $100 within ten days and has traded between $110 and $119 through late March.[3] As of 30 March it topped $116 following Iranian warnings of a possible US ground invasion and escalation into Lebanon.[4] Wood Mackenzie analyst Simon Flowers has written that $200 per barrel is “not outside the realms of possibility” if the disruption persists.[1]

The shock has hit Asia hardest. Japan sources 90% of its oil from the Middle East. South Korea sources 70%.[5] Southeast Asian nations import between 60 and 95% of their crude supply from the region.[6] Governments across Asia have responded quickly, and some of those responses have direct implications for how and where people work.

What governments have done

The policy responses share a common logic: reduce commuting to conserve fuel. Sri Lanka declared every Wednesday a public holiday for government institutions, schools, universities, and courts from 18 March 2026, with private organisations asked to follow.[7] Officials put remaining fuel reserves at roughly six weeks when the measure was announced.

The Philippines ordered public sector employees to attend the office only four days per week, giving agencies the choice of a common work-from-home day or a compressed four-day week.[8] Pakistan introduced a four-day government work week alongside school closures and a ban on all in-person public sector meetings, which moved online.[9]

Thailand told civil servants not involved in frontline service delivery to work from home entirely, mandated air conditioning at 27 degrees Celsius, and encouraged office workers to wear short-sleeved shirts to allow buildings to reduce cooling further.[10] Vietnam and Myanmar introduced their own fuel austerity measures, while South Korea announced a price cap on petroleum products.[5]

Outside Asia, the response has been softer but not absent. Workers in Australia are being encouraged to work from home where possible as the government weighs economic pressure from the conflict.[11] The UK has issued similar guidance. The IEA has formally recommended that all governments encourage workers to stay home to reduce oil consumption from commuting.[12]

2. Why some of this may be permanent, and why some will not be

The comparison most analysts are drawing is to COVID-19. Remote work in early 2020 was framed as a temporary emergency measure. It was not. Within 18 months, hybrid work had become a standard expectation for knowledge workers globally, and the majority of organisations never fully reversed it.

Writing in Fortune, Mercer’s chief workforce strategist William Self identified what distinguishes this moment from previous energy shocks. For the first time, two previously separate conversations are happening simultaneously and reinforcing each other: emergency government mandates and voluntary employer adoption of four-day weeks.[13] The UK ran the world’s largest four-day week pilot in 2022. CIPD research indicates the model has the potential to become a new global norm, with voluntary trials already underway across North America, Europe, Asia-Pacific, and the Middle East.[13]

The ExpatGo analysis adds a structural dimension: the oil crisis is one of three converging forces rather than an isolated shock. AI is reshaping what productivity means and how it is measured. Rising living costs are prompting workers to reconsider the trade-off between office attendance and take-home pay. And government mandates in multiple countries are proving, at scale, that compressed work schedules are operationally viable.[14] All three forces push in the same direction.

There are genuine equity questions worth sitting with alongside the structural analysis. A four-day week is far more viable for office-based knowledge workers than for those in logistics, healthcare, retail, or manufacturing. If compressed weeks become standard for some roles but not others, organisations will need to navigate fairness considerations that hybrid work has only partly resolved. These are not reasons to dismiss the trend. They are reasons to think about it with some nuance.

3. The overlooked operational reality

Most discussion of the Iran War’s workplace implications sits at the policy and economics level. An aspect that has received less attention is what compressed attendance actually means for the people responsible for running an office day to day.

A four-day work week does not reduce the complexity of managing a shared workplace. In many respects it concentrates it. If employees who currently spread attendance across five days shift to four, demand for desks, meeting rooms, visitor facilities, and parking is compressed into a shorter window. The midweek peak that already exists in hybrid office data (attendance on Tuesday to Thursday significantly outpacing Monday and Friday[15]) becomes more pronounced, and the gap between peak and trough days widens.

This is worth examining carefully, because it plays out differently depending on how well a workplace is set up to absorb variable demand. Organisations with good visibility into real-time occupancy, flexible booking policies, and reliable data tend to navigate these shifts more smoothly than those managing primarily through manual processes or fixed allocation. That was true during the transition to hybrid work, and it is likely to be true again.

Professor Rivkin raised a related point: if a four-day week applies to knowledge workers but not frontline staff, the result is a fragmented workplace with different groups operating on different schedules.[13] Managing that without clear visibility of who is in and when is a genuine coordination challenge, and one that many facilities teams are only beginning to think through.

4. Considerations for workplace leaders

Whether or not a four-day week becomes relevant to your organisation in the near term, the current moment is a useful prompt. The question worth sitting with is not whether to act now but whether your current workplace infrastructure would hold up under a meaningful change in attendance patterns, and what gaps would surface if it did not.

Visibility before policy

One of the clearest lessons from the hybrid work transition is that organisations which invested in workplace visibility early were better equipped to make policy decisions with confidence. Knowing what is actually happening in your office (which days are genuinely busy, which spaces are underused, where friction is appearing) is the foundation for any sensible response to changing attendance. Policy built on that data tends to hold. Policy built on assumptions tends to drift.

Flexibility in how space is configured and allocated

Static desk allocation and rigid room booking policies were the first things to create problems when hybrid work arrived. The same pattern is likely if attendance compresses further. Organisations that have already moved toward flexible booking, neighbourhood-based seating, and dynamic room policies are better positioned to absorb shifts in demand without rebuilding from scratch.

The equity dimension

If different parts of your organisation move to different attendance models (some teams on four days, others on five, some roles unable to compress at all) the equity questions become more visible. Who has access to flexibility? Are in-office requirements evenly applied? Does the office experience hold up across teams with different patterns? These are worth thinking through before attendance models diverge rather than after.

Data for leadership conversations

Any significant change in how people use the office will eventually surface as a leadership conversation about space, cost, and property decisions. Facilities and workplace teams that can bring real utilisation data to those conversations are in a materially different position from those responding with estimates. The preparation for that conversation starts with the data collection in place today, not at the point the question is asked.

5. Questions worth asking about your current setup

Rather than a prescriptive checklist, these are the questions that facilities, HR, and operations leaders are finding useful to work through as attendance patterns continue to evolve. They are intended as prompts for discussion rather than a verdict on readiness.

At HybridHero, we work with facilities and workplace teams navigating exactly these kinds of transitions. We have seen how real-time visibility and flexible booking reduce friction when attendance patterns shift, though every organisation’s situation is different. If any of these questions surfaced something worth exploring, the free Workplace Utilisation Audit Kit is a practical starting point. It takes under 30 minutes and does not require any commitment.
