Everything you need to know about flexible and temporary labour.

Flexible (or temporary) labour is a model where you bring in skilled trades and operatives for a defined period or scope, instead of adding permanent headcount. On a construction programme that means steel fixers, MandE operatives, groundworkers and supervisors deployed exactly when and where the work demands them.

Contingent workers aren’t on your payroll — they’re sourced, vetted, paid and managed through a labour partner like RTB. Contractors use flexible labour for a range of reasons:

• covering a surge or ramp-up — hitting a pour date or a fit-out deadline
• filling a short-term skills gap without a permanent commitment
• trialling trades on real site work before a permanent move
• flexing crews up and down as the programme moves between phases
• accessing specialist skills fast, in any market

Construction demand is volatile and programmes rarely run exactly to plan. A flexible labour strategy gives your sites the resilience to absorb change — without the cost, delay and risk of a permanent hire every time the workload shifts.

In 2026, the sharpest contractors pair flexible labour with data. AI-assisted workforce planning now helps forecast crew demand against the programme, so you mobilise the right trades at the right moment — not too early, not too late, and never short on a critical pour.

Proven benefits

• fast, affordable access to specialist trades
• pay only for the labour you need, when you need it
• an edge over competitors running rigid, permanent-only crews
• trial potential permanent hires on live site work
• absorb cyclical swings and short-notice demand

Now that flexible labour is a core asset rather than a last resort, you can build a strategy that leverages it. Start by mapping where flexibility helps most across your programme — which roles flex with the phases, and which should stay permanent.

How to get started

• map your programme peaks and the trades each phase needs
• set your compliance standard — right-to-work, tickets, insurances
• decide your split of permanent core vs. flexible crews
• use workforce data to forecast demand ahead of mobilisation
• choose one labour partner who can scale with you

Even if you only need flexible labour for one package today, the relationship you build can support the wider needs of your programme tomorrow.

Good trades have options. Retention starts off the tools — with welfare, accommodation, fast and reliable pay, and a partner who treats workers like the professionals they are. Over time you build a “contingent talent brand” that the best operatives want to work under.

Contingent trades tend to look for:

• a steady pipeline of work across sites and seasons
• proper welfare, accommodation and transport sorted before day one
• fair, on-time pay and transparent terms
• progression — from operative to ticketed specialist to supervisor
• respect, safety and a partner that has their back

Many contractors try to manage flexible labour themselves, sourcing operatives directly. That can work for one or two at a time — but those relationships are tenuous and hard to cultivate as you scale.

A dedicated partner has the knowledge, the workforce and the systems to become a genuine strategic solution. The right one doesn’t just supply bodies; it manages compliance, welfare and logistics, and gives you a single point of contact across every trade and market. The key questions to ask:

• Can they mobilise the trades I need, at the pace my programme demands?
• Do they own the compliance — right-to-work, tickets, payroll?
• Can they scale across multiple sites and countries?
• Do they look after the workforce well enough to retain it?
