Temporary Staffing
Definition
Temporary staffing is the practice of filling short-term or fluctuating labor needs with workers employed by a staffing agency and assigned to a client's site for a limited period. The agency recruits, employs and pays the temp worker; the client directs daily work and pays the agency an hourly bill rate.
Also called: Temp staffing, Temporary employment, Temp work, Temporary help services
Formula
Cost premium of a temp = (Bill rate − Fully loaded direct hourly cost) × Hours worked
- Bill rate
- The hourly rate the client pays the staffing agency.
- Fully loaded direct hourly cost
- What the same worker would cost as your own employee per hour: wage plus payroll taxes, workers' compensation, benefits and paid leave, plus recruiting and onboarding spread over expected tenure.
- Hours worked
- Total hours on assignment in the period being compared.
Worked example
A food manufacturer pays $27 an hour for temporary packers whose pay rate is $18. Its own packers at $18 an hour cost about $24 fully loaded once taxes, benefits, paid leave and recruiting are included. The temp premium is $3 an hour. For a 10-week peak at 40 hours a week, that is $1,200 per worker, which is cheaper than hiring, training and then laying off direct employees. For a role filled all year, the premium becomes about $6,240 per worker, and converting to direct hire usually makes sense.
How temporary staffing works
The client places a job order with a staffing agency: role, number of workers, shifts, pay rate, start date, expected duration, physical demands and safety requirements. The agency recruits and screens candidates, runs any agreed checks, completes hiring paperwork, and sends workers to the site. Each week the client approves hours, the agency pays the worker and invoices the client at the agreed bill rate.
Assignments range from a single day (common in event, hospitality and light industrial work) to many months. Either the client or the worker can usually end an assignment at short notice. Workers stay employed by the agency between assignments only if the agency has another assignment for them.
When temporary staffing makes sense
- Seasonal or predictable peaks: retail and parcel peaks, agricultural harvests, tax season, open enrollment for benefits call centers.
- Uncertain or short-lived demand: a new contract that may not renew, a backlog to clear, a system migration.
- Covering absences: leaves of absence, vacancies while you recruit a permanent hire.
- Ramping up a new site faster than your recruiting team can hire directly.
- Evaluating fit: temp-to-hire arrangements let both sides try the job before committing.
Temporary staffing works less well for roles with long training periods, roles requiring deep knowledge of your systems or customers, and roles you clearly need all year. In those, the premium adds up and churn among temps erodes quality.
Temp worker rights and employer obligations
Temporary workers are employees, of the agency and in some respects of the client. Federal wage and hour law under the FLSA applies, including minimum wage and overtime for non-exempt workers. Anti-discrimination laws protect temps, and the client can be liable for discrimination or harassment it controls at its site. OSHA treats safety of temporary workers as a shared responsibility: the host employer typically provides site-specific training and hazard protection, and the agency must make sure the host is meeting its obligations.
Several states go further. Illinois' Day and Temporary Labor Services Act includes notice requirements and, after amendments in 2023, equal pay and benefits provisions for temps assigned to a client for more than 90 days. New Jersey's Temporary Workers' Bill of Rights adds pay parity and notice requirements for certain temporary laborers. Massachusetts requires agencies to give workers written job details. Under the ACA, the agency is usually responsible for offering coverage to eligible full-time temps, which the bill rate should reflect. Rules vary by state; check them before contracting.
The shared responsibilities are often called co-employment.
Temporary staffing in high-volume operations
Large warehouses, distribution centers and contact centers often run a blended workforce: a core of direct employees plus a temporary layer that flexes with volume. This is part of managing a contingent workforce. A few practices make it work:
- Forecast with the agency. Share weekly volume forecasts so agencies can recruit ahead of peaks rather than scramble.
- Set a conversion path. Tell temps on day one how they can be hired permanently and what performance is needed. Conversion programs are one of the cheapest sources of proven direct hires.
- Standardize onboarding. Temps should get the same safety training and the same quality standards as employees.
- Measure by agency: fill rate, first-day show rate, assignment completion, safety incidents, and conversion rate.
Common mistakes
- Permanent temps. Keeping the same temp in the same role for years costs more and increases co-employment risk.
- Treating temps as second class: separate break areas, no recognition, no information about conversion. It raises turnover and safety risk.
- Ordering with vague job details. Agencies fill the job you describe. If the role requires lifting 50 pounds repeatedly in a freezer, say so.
- Comparing only bill rates. A cheaper agency with a 30 percent first-week no-show rate costs more in overtime and lost output.
- No exit planning at the end of a peak, which leads to rushed assignment endings and poor reputation with the local labor pool.
Frequently asked questions
What is temporary staffing?
Temporary staffing is filling short-term or variable labor needs with workers employed by a staffing agency and assigned to a client's workplace for a limited time. The agency pays the worker and bills the client an hourly rate.
How does a temp agency work?
The client tells the agency what workers it needs. The agency recruits, screens and hires workers, sends them to the client's site, pays their wages and taxes, and invoices the client for hours worked at an agreed bill rate.
Is a temp worker an employee?
Yes. A temp worker is usually an employee of the staffing agency, which handles pay and taxes. The client directs the work and can share legal responsibility for safety, working conditions and some discrimination claims.
How long can a temporary employee work for a company?
There is no general federal limit in the US. Some states and many client contracts set limits or add requirements after a period, such as pay parity after 90 days in Illinois. Many companies cap assignments to manage cost and co-employment risk.
Is temporary staffing more expensive than hiring directly?
Per hour, usually yes, because the bill rate includes the agency's costs and margin. For short peaks, though, temporary staffing is often cheaper overall because you avoid recruiting, training, benefits and separation costs for short-term roles.
