Part of the staffing & recruitment agency hub — an educational cluster covering how agencies work, the placement models and how employers and candidates work with them. For decision-style reading, see the staffing & hiring comparisons.
This page explains, in plain English, what a staffing agency is, how it differs from related agencies, and where it fits in the wider hiring picture. It is educational and neutral — not a ranking, a recommendation of any provider, or legal advice.
Who this page is for
- Employers weighing whether to use a staffing agency for short-term or variable demand
- Founders and managers making their first temporary or seasonal hires
- HR teams that need to explain staffing models to internal stakeholders
- Job seekers deciding whether to register with a staffing agency
Core concept
At its core, a staffing agency acts as an intermediary between people looking for work and organisations that need workers. It maintains a pool of available candidates, matches them to client requirements, and handles much of the administrative side of placing them.
In a typical temporary arrangement the agency holds the employment relationship: it pays the worker, manages timesheets and handles payroll administration, while the worker performs the day-to-day job under the client’s direction. The client pays the agency for the hours worked rather than employing the person directly.
Some staffing agencies are generalist and cover many sectors; others specialise in a single field such as industrial, healthcare, hospitality or office support. Specialisation often means a deeper candidate pool and a better feel for the roles involved.
How it works
- The client describes the role, the skills needed, the location and how long the work is expected to last
- The agency searches its existing pool and may advertise to attract additional candidates
- Candidates are screened, and suitable people are put forward to the client
- The worker starts the assignment; in temporary models the agency remains the employer of record
- The agency handles timesheets and payroll administration, and the client is invoiced for the work
Plan the hire before you source with the recruitment planning checklist, and keep screening consistent using the candidate screening checklist.
Key considerations
- Whether you need temporary cover, a contract resource or a permanent hire — agencies handle these differently
- Who holds the employment relationship and the day-to-day responsibilities during the assignment
- How clearly you can describe the role, because vague briefs produce mismatched candidates
- How the agency screens and what checks it carries out before putting people forward
- How conversion to a permanent role would work if an assignment goes well
Advantages
- Access to workers quickly when demand is urgent or seasonal
- Reduced internal administration for short-term hires
- A flexible way to cover absence, peaks or one-off projects
- A route to assess someone on an assignment before considering a permanent role
- Useful reach into pools you may not advertise to directly
Trade-offs
- A fee or markup is built into the cost of the work
- Day-to-day communication may run partly through the agency
- Workers may need time to learn your systems and culture
- Quality and specialisation vary between agencies
- It is less suited to building a stable, long-tenured core team
Common mistakes
- Treating "staffing", "recruitment" and "employment" agencies as the same thing
- Briefing the agency vaguely and then judging the candidates harshly
- Assuming the agency carries every check you need without confirming what it actually does
- Overlooking who is responsible for supervision, equipment and safety on site
- Using temporary staffing for a genuinely permanent need and paying for it repeatedly
Practical checklist
- Define the role, duration and must-have skills before you contact an agency
- Confirm whether you want temporary, contract or permanent placement
- Ask which screening and checks the agency performs as standard
- Clarify who is the employer of record during the assignment
- Agree how performance issues and replacements are handled
- Document how a temp-to-permanent conversion would work
