The idea of reducing working hours in a sector already facing labour shortages may sound counterintuitive. Yet conversations around a four day working week are gaining momentum across industries, and construction is no exception.

Pira Rajenthira, Contract Administrator at Clough Group, recently argued that shorter working weeks could bring substantial benefits to construction. His reasoning is straightforward: the industry’s reliance on long hours and high pressure environments is unsustainable, and a shift to four days could improve safety, morale and mental health.

 

Safety and Wellbeing Benefits

Fatigue remains one of the biggest risks on construction sites. Shorter working weeks could mitigate this by reducing the likelihood of accidents and errors. In addition, employees would gain a stronger work life balance, contributing to improved mental health which the sector increasingly recognises as critical.

 

A Tool for Recruitment and Retention

Construction companies have long struggled to attract and retain talent, particularly younger workers who place greater value on flexibility. Offering a four day week could provide a significant competitive advantage. Evidence from other industries suggests job applicants are more likely to apply to organisations trialling reduced hours, making it a valuable lever in a tight labour market.

 

Productivity and Engagement

There is a common assumption that fewer hours lead to lower output. However, research shows the opposite is often true. Trials of four day working weeks have reported employees taking fewer sick days, enjoying better health overall and experiencing higher job satisfaction, with no decline in productivity. For employers, this presents an opportunity for both immediate and long term gains.

 

Challenges to Implementation

Practicalities remain a challenge. Site based work is closely tied to project timelines, client demands and regulatory requirements. Condensing hours into four days could strain already stretched teams. Flexible models such as staggered schedules, hybrid approaches for office staff, or seasonal adjustments may prove more realistic than a single solution across the board.

 

Looking Ahead

The conversation around flexible working is not going away. As Rajenthira highlights, construction firms that embrace change early may find themselves better positioned to attract talent, improve safety and enhance workforce wellbeing. Whether through a four day week or other innovative approaches, the industry has an opportunity to redefine how work is structured.

These conversations matter because change in construction rarely happens in isolation. It takes a community to drive new ideas forward. At London Build 2025, thousands of industry professionals will have the chance to network, exchange perspectives and openly discuss challenges such as mental health, diversity and the future of working practices. The Ambassador programme in particular creates a platform where lived experiences can be shared, and where practical solutions can be explored collaboratively. It is only when people come together, speak honestly and build connections that lasting change becomes possible.
