Across the UK's built environment, a growing risk is sitting inside project teams. Six in ten specialist contractors now manage people in some form. Eight in ten have never received any leadership or management training to do it. Our snapshot survey of 482 contractors and hiring managers points to the rise of the "accidental manager", and it's widening the very capability gap employers are working hard to close.
How contractors became managers by default
For 40% of contractors, managing people is a formal part of the role. A further 20% do it unofficially, coordinating teams, mentoring juniors, owning delivery, without it ever appearing in a job description. Either way, the responsibility is real. The training rarely follows.
Only around 18% of employers offer leadership or management development as standard. Roughly a third provide it only when a specific need arises, and roughly a third offer nothing at all. The result is a large population of technically excellent professionals asked to lead people and manage delivery with no preparation for that part of the job.
Why "accidental" is a delivery risk, not just a training gap
Employers can feel the consequences even when they can't always name the cause. Leadership and people-management skills are now among the hardest capabilities to find, cited by 42% of hiring managers, increasingly rated alongside technical and engineering expertise rather than behind it. Communication and team collaboration follow close behind.
These are exactly the skills the accidental manager is expected to supply, and exactly the ones nobody trained them in. When they're missing, projects rarely fail outright; they get harder. Stakeholders are managed less smoothly, teams are coordinated less effectively, and pressure lands on a small number of experienced people who are already stretched thin.
The hybrid complication
Leadership and delivery experience have traditionally been passed on informally, on site, in the room, by watching someone more senior handle a difficult client or a tricky decision. As contractors increasingly work hybrid or remotely, that incidental learning happens less often. The skills the accidental manager needs most are the ones hardest to pick up at a distance.
Meeting contractors' expectations on flexibility while still developing their leadership capability is one of the defining workforce challenges our research identified.
James Fernandes, Co-Founder and Managing Director at Carrington West, puts it plainly: "There is a risk that organisations end up creating accidental managers because projects still need to be delivered. Employers need to think more strategically about leadership development, mentoring and succession planning if they're going to build a sustainable talent pipeline for the future."
Turning it around
The fix isn't complicated, but it does need to be deliberate. Offering management training as standard rather than on request, building mentoring and knowledge-sharing into hybrid working, and identifying the accidental managers already in your teams are all practical first steps.
The alternative, leaving leadership capability to develop by chance, is how today's manageable strain becomes tomorrow's leadership gap.
