Why the skills shortage is a growing safety problem
Workforce pressure across high-risk industries is quietly becoming one of the biggest safety risks.
Somewhere on a major infrastructure project right now, a supervisor is covering ground they shouldn’t have to cover alone. Their experienced colleague moved to another site last month. The new recruit is capable, but they’re two weeks in. And the schedule hasn’t changed.
The conversation about skills shortages usually centres on productivity, project delivery and economic growth. But for many Safety Directors, the workforce gap has another dimension that receives far less attention: its direct impact on safety performance.
What the research shows
Recent industry analysis across energy, water and construction suggests workforce availability – or the lack of it – is becoming one of the defining operational risks for project delivery over the next decade.
UK water sector alone could face a shortfall of around 44,000 workers by 2030, potentially affecting operational resilience and project delivery. At the same time, wider analysis of the green economy warns that shortages in hard engineering skills could become one of the biggest barriers to delivering the energy transition. Meanwhile, the UK’s net-zero construction workforce may already be at risk of burnout due to sustained delivery pressure and skills gaps.
From energy infrastructure programmes to water utilities and major construction upgrades, the scale and pace of delivery required to meet national infrastructure and net-zero ambitions is both sizeable and accelerating. Yet the number of experienced workers able to deliver this work isn’t expanding at the required pace.
For many safety leaders, the signs are already visible: supervisors stretched across projects, new workers learning faster than experience normally allows, and operational teams carrying increasing delivery pressure.
The engineering ambition is clear. The human system delivering it is under increasing pressure.
How workforce pressure changes the operating environment
The impact of workforce shortages may not immediately appear on the safety dashboard. Yet beneath the surface, the dynamics of a stretched workforce can begin to change how work is actually carried out. A shortage of experienced personnel can subtly alter the operating environment in several ways.
Experienced supervisors may be responsible for larger teams or multiple sites. New or less experienced workers may enter high-risk environments faster than traditional competency pathways would allow. Contractor cohorts may rotate more frequently, making consistent safety culture harder to establish. Operational teams may work under increased time pressure to maintain programme schedules.
None of these factors automatically leads to incidents. But they do change the conditions in which safety leadership operates. Over time, those conditions can begin to influence behaviours, decision-making and risk tolerance on the ground.
For Safety Directors, this creates a leadership challenge that sits somewhere between workforce planning, operational resilience and culture.
Where safety leadership makes the difference
The organisations that navigate this well don’t treat workforce pressure as a reason to lower the bar on safety culture. They treat it as a reason to raise their investment in it.
In practice, that means paying close attention to how new workers enter high-risk environments — not just whether they’ve completed the right courses, but whether they genuinely understand the culture they’re stepping into and what’s expected of them when things get difficult.
It means supporting supervisors more deliberately. Supervisors sit exactly where operational pressure and safety expectations collide. When they’re stretched, the quality of safety conversation on the ground — the challenge, the intervention, the moment someone says “wait, something’s not right here” — is what’s at stake. Giving them the confidence and the language to lead in those moments isn’t a soft skill. It’s a critical control.
And it means being honest about what contractor integration actually requires. A rotating workforce doesn’t absorb safety culture by osmosis. It needs deliberate, repeated, human engagement; the kind that sticks long after the training day.
The workforce challenge ahead is real and it isn’t going away. But the organisations that treat it as a prompt to strengthen their safety leadership infrastructure, rather than just manage their headcount, will be better placed on every measure that matters.
Safety culture is now a programme requirement
The way major infrastructure programmes think about safety has shifted fundamentally over the past decade.
The Construction Playbook — mandatory for all central government departments and their arm’s-length bodies — now requires contracting authorities to specify safety as an outcome, not a compliance condition. Project 13, the enterprise delivery model developed by the Institution of Civil Engineers and adopted by some of the UK’s largest programme owners, goes further: it identifies safety culture as central to making integrated, long-term supply chain relationships actually work.
These aren’t aspirational frameworks. They are shaping how ITTs are written, how supply chains are contracted, and what Delivery Partners are expected to demonstrate before a single spade goes in the ground.
What that means in practice is that safety culture infrastructure – the inductions, the leadership programmes, the immersive environments where workers genuinely engage with risk rather than sit through it — is moving from a discretionary spend to a specified outcome.
The Sellafield Programme and Project Partners model already includes an annual supply chain safety day as a programme-level commitment. Tideway showed what happens when you design safety culture in from the start: well over 40 million hours worked, zero fatalities, zero major life-changing accidents.
As the UK’s £718bn infrastructure pipeline mobilises — in energy, water, rail, and health — the programmes that get this right early will set the standard. The ones that don’t will find the regulator, the workforce, and the public asking why they didn’t – and perhaps find it increasingly hard to recruit the workers that are so essential to these projects.
A reminder for the months ahead
None of this will be unfamiliar to experienced Safety Directors. The interaction between regulatory environment, workforce capability, leadership and safety outcomes has always been part of the job.
What is changing is the scale and pace of the requirements.
Large infrastructure programmes will continue to accelerate over the coming years. Alongside the engineering challenge sits a human one: ensuring the workforce delivering that work has the experience, confidence and leadership support required to operate safely.
For many organisations, the most important safety conversations are therefore shifting significantly – from simply managing hazards, to understanding how workforce capability, leadership and culture interact under pressure.
Because when the workforce system is stretched, the strength of safety leadership becomes one of the most important controls an organisation has.
ATT works with safety leaders across construction, energy and water to build the leadership capability that holds when everything else is under pressure. If that’s a conversation worth having, we’re here.
