Quiet hiring: how UK employers fill skills gaps

Job postings are down, skills shortages are not, and most HR teams are being asked to do more without adding headcount. Quiet hiring is how many UK employers are closing that gap, by building capability from the people they already have rather than recruiting from outside.

Quiet hiring is the practice of filling skills gaps without traditional external recruitment, either by moving and developing existing employees or by bringing in short-term contractors. The term is new, but the idea is not: it formalises upskilling, stretch assignments, and internal moves into a deliberate workforce strategy. Gartner ranked it number one on its future of work trends, and it has stuck as budgets tightened.

In practice, quiet hiring shifts the first question from “who can we recruit?” to “who already works here and could grow into this?” That reframing matters most when hiring is slow and skills are scarce.

Quiet hiring and quiet quitting point in opposite directions. Quiet hiring is an employer strategy to gain skills without new full-time hires. Quiet quitting is an employee response, where someone does the minimum their role requires and nothing more. One is about building capability; the other is about withdrawn effort.

The two are linked. Employees who feel overloaded by added responsibilities with no recognition can disengage, which is how poorly run quiet hiring feeds quiet quitting. Done well, the reverse happens: clear growth opportunities tend to lift engagement. UK research suggests around one in five employees are quiet quitting, so the risk of getting this wrong is real.

Quiet hiring takes two main forms, internal and external, and most employers use a mix. The internal route develops or moves existing staff. The external route brings in temporary skills for a defined need.

• Internal quiet hiring: redeploying employees into priority roles, assigning stretch projects, and upskilling people to cover new requirements.
• External quiet hiring: engaging contractors, freelancers, or interim specialists for time-bound work without adding permanent headcount.

Internal quiet hiring builds long-term capability and retention. External quiet hiring gives fast access to a specific skill. The right choice depends on whether the gap is permanent or temporary, and whether that expertise already exists somewhere in the organisation.

UK employers are turning to quiet hiring because hiring has slowed while skills shortages have widened. The CIPD’s Labour Market Outlook reported hiring intentions at a record low outside the pandemic, and ONS data put UK unemployment at 4.9% in early 2026, up over the year. Rising employment costs, including the national living wage increase, add further pressure to control headcount.

Skills shortages compound the problem. The CIPD reports that competition for well-qualified talent has increased, with most employers struggling to attract suitable candidates. When you cannot easily recruit the skill you need, building it internally becomes the faster option.

There is a planning risk, too. Cutting roles and then rehiring months later for the same skills is expensive, and it wastes knowledge the business already paid for. Quiet hiring, done deliberately, keeps that capability inside the organisation instead.

The main benefit of quiet hiring is faster, cheaper access to skills than external recruitment, alongside stronger retention. Existing employees already know the systems, clients, and culture, so they reach productivity sooner than an outside hire. For employees who want to grow, new responsibilities can be a genuine opportunity.

• Lower cost than recruiting, onboarding, and training a new permanent hire.
• Faster time to productivity, because internal movers already understand the business.
• Higher retention, as employees who see progression are more likely to stay.
• A broader skills base, as people develop capability across teams and functions.

These benefits only hold when the extra work is recognised and fairly rewarded. Without that, the savings are short-lived.

The biggest risk of quiet hiring is overloading employees, which drives burnout and turnover. Piling responsibilities onto high performers without more pay, a title change, or support can backfire, and the people you most want to keep are usually the first to leave. Other risks weaken the same outcome.

• Fairness concerns, if there is no clear, visible criteria for who gets stretch opportunities.
• Hidden gaps, because moving someone into a priority role can leave a hole in their old team.
• Reduced diversity, when employers stop bringing in external talent and recruit only from within.
• Pay disputes, where added duties are not matched by added reward.

Each risk is manageable with planning. None of them disappears on its own.

Quiet hiring is legal in the UK, but changing someone’s role or duties has employment law implications. Minor adjustments usually sit within an employee’s existing contract. Significant changes to duties, hours, or pay are a variation of contract, which generally needs the employee’s agreement rather than a unilateral imposition.

Two points matter for UK employers. A material change to terms may require an updated written statement of employment particulars. And asking employees to take on substantially more work without fair reward can damage trust, fuel grievances, and increase legal risk. Acas guidance on changing an employment contract is the right reference point before making formal changes.

Quiet hiring works when it is planned, transparent, and fairly rewarded, rather than used as a quiet way to extract more for less. A structured approach protects both the strategy and the people in it.

1. Map your skills gaps so you know exactly what capability you need and where.
2. Audit existing skills to see who could grow into the gap or move across into it.
3. Decide internal or external for each gap, based on whether it is permanent or temporary.
4. Talk to the employee openly about why the move matters and what it leads to.
5. Match added responsibility with reward, whether pay, a title change, or development.
6. Backfill the gap left behind so the original team is not quietly stretched.
7. Review regularly and give people a route back if the fit is wrong.

Treating quiet hiring as a structured part of workforce planning, not an informal shortcut, is what separates a retention win from a burnout risk.

Quiet hiring belongs inside a connected talent strategy, not bolted on as a standalone fix. It draws on the same foundations as redeployment and career development: a clear view of the skills you have, the gaps you face, and the paths between roles. Without that visibility, quiet hiring becomes guesswork.

The same skills mapping that powers internal quiet hiring also supports redeployment when roles change, and feeds career progression that keeps people engaged. When external recruitment is slow and skills are scarce, employers who can see and move their own talent hold a real advantage.

Quiet hiring is the wrong choice when the gap is permanent and large, when no one internal is close to the skill, or when your team is already stretched. Forcing an internal move in those cases delays the work and risks burnout. A permanent senior gap, a regulated specialism, or a long-term capacity shortfall usually calls for a proper hire instead.

An employee can usually refuse duties that fall outside their contract, because a significant change needs their agreement. Minor adjustments often sit within existing terms, but a material shift in role, hours, or pay is a variation of contract. Imposing it without agreement can lead to grievances or breach of contract claims, so consultation matters.

A promotion is a permanent move to a higher role with matching pay and title, agreed openly. Quiet hiring is broader and often informal: it can mean a temporary stretch project, a sideways move, or added duties that may or may not come with reward. The risk is that quiet hiring quietly becomes an unpaid promotion, which is where trust breaks down.

Track internal fill rate, retention among people who moved, and how quickly they reach full performance compared with external hires. Watch engagement and workload signals too, since rising absence or turnover among stretched staff is an early warning. If internal moves are faster and cheaper than recruiting and people stay, the approach is working.

Quiet hiring can work well in a small business, where people often already cover several functions and gaps appear fast. The same rules apply: be clear about what is changing, reward added responsibility, and avoid loading everything onto one person. With a small team, backfilling matters even more, because one overstretched employee leaving has a bigger impact.
