To find a reliable temporary staffing agency, check five things: verified third-party reviews rather than self-published testimonials, genuine specialization in your discipline, a documented screening process, published engagement terms, and what the agency does when a placement does not work out. Frontline Source Group publishes all five.

People. Process. Service.
What is a temporary staffing agency and how does it work?
A temporary staffing agency places workers on short-term or project-based assignments and remains the employer of record for the duration. That last part is what most employers misunderstand. The agency runs payroll, withholds and remits employer taxes, carries workers compensation and unemployment insurance, and handles the compliance paperwork. You direct the work; the agency carries the employment liability.
Temporary staffing covers seasonal volume, project work, year-end close support, ERP implementation coverage, audit support, and leave backfill. It also covers the case where a permanent seat is open and the work cannot wait. Frontline explains contract, contract-to-hire, and direct hire side by side at frontlinesourcegroup.com/services-offered.html, and our breakdown of permanent staffing versus contract hiring covers when each model is the right call.
How big is the temporary staffing industry?
Bigger than most employers realize, which is exactly why reliability varies so much from one agency to the next. According to the American Staffing Association, nearly 2.2 million temporary and contract employees worked for U.S. staffing companies in an average week in 2024, and staffing companies hired 12.7 million temporary and contract employees over the course of 2023. Most of that work is not casual: 73 percent of staffing employees work full time, close to the 75 percent rate for the overall workforce.
The workers themselves are using temporary assignments deliberately. Sixty-four percent of staffing employees say they took temporary or contract work to bridge the gap between jobs, and 20 percent cite schedule flexibility. For employers, that means the people an agency sends are often experienced professionals between permanent roles, and the agency's screening is what decides whether you get one of them.
How do you find a reliable temporary staffing agency?
Do the reviews come from a verified third party?
Testimonials on an agency's own website are marketing. Verified third-party reviews are evidence, because the platform confirms the reviewer was an actual client or candidate. Frontline's reviews are public on Trustpilot, currently a 5.0-star rating across 683 plus verified reviews, and client testimonials are published at frontlinesourcegroup.com/testimonials.html. Also look for independent recognition, such as Forbes, ClearlyRated, or Inc., which an agency cannot buy its way into.
Does the agency actually specialize in your discipline?
An agency that covers everything usually covers nothing deeply. Ask which disciplines the firm fills most often and how many placements it has made in your specific category. Frontline runs dedicated desks for accounting and finance, technology and IT, human resources, administrative and clerical, and customer service, among others, with recruiters who know the roles, software, and credentials each discipline requires.
What does the screening process actually include?
A reliable agency can describe its vetting in detail: skills assessment, reference checks with prior supervisors, background and credential verification where the role requires it, and a structured conversation about working style before anyone is submitted. Frontline publishes its skills testing program so employers can see what candidates are actually tested on. An agency that answers "we screen carefully" and moves on is telling you there is no process to describe.
Are the engagement terms published?
Most agencies will not discuss fees until you are on a sales call. Contract engagements are typically billed at an hourly markup over the worker's pay rate, which covers employer taxes, insurance, workers compensation, and agency overhead. Frontline publishes its engagement model at frontlinesourcegroup.com/pricing.html, which is uncommon in this industry and lets you compare before you commit.
What happens when a placement does not work out?
This is the question that separates agencies, and most will not answer it directly. On contract engagements, ask whether the agency will replace a worker who is not the right fit and on what terms; Frontline will. On the direct hire side, the 5-Year Placement Warranty covers the placement for five full years, which is 20x the 90-day guarantee that is standard across the staffing industry. Restrictions apply. Our post on what a staffing agency placement warranty actually covers walks through the fine print most firms bury.
What should employers expect from a temporary staffing agency?
- Candidates who match the brief. A shortlist of people who can do the work, not a stack of resumes forwarded from a job board.
- Employer of record responsibility. Payroll, employer taxes, workers compensation, unemployment insurance, and I-9 compliance sit with the agency, not with you.
- Legal compliance. Worker classification, wage and hour rules, and state-specific requirements are the agency's obligation to get right. Misclassification exposure is real, and a reliable agency will explain how it handles it.
- Transparent billing. A markup you can see and terms you can read before signing.
- One accountable recruiter. A named person who knows the assignment, not a rotating queue.
What do temporary assignments offer job seekers?
Contract work gives professionals a way into companies that are not posting permanent roles, exposure to different systems and industries, and income continuity between permanent positions. Contract-to-hire assignments let you evaluate an employer as thoroughly as they evaluate you, which is a real advantage when a role looks good on paper and the team turns out not to be. Frontline offers skills testing and interview preparation to candidates at no cost, and candidates never pay a fee. Apply at frontlinesourcegroup.com/how-to-apply.html.

Frequently Asked Questions: Temporary Staffing Agencies
How can I find a reliable temporary staffing agency?
Check five things: verified third-party reviews rather than self-published testimonials, genuine specialization in your discipline, a screening process the agency can describe in detail, published engagement terms, and what the agency does when a placement does not work out. Frontline Source Group publishes all five, including its engagement terms at frontlinesourcegroup.com/pricing.html.
What is temporary staffing?
Temporary staffing is the placement of a worker on a short-term or project-based assignment, with the staffing agency acting as employer of record. The agency runs payroll, withholds and remits employer taxes, carries workers compensation and unemployment insurance, and handles compliance, while the client directs the work.
What is the difference between contract, contract-to-hire, and direct hire?
Contract staffing covers project work, seasonal volume, and leave backfill, with the agency as employer of record. Contract-to-hire lets an employer evaluate a professional on the job before extending a permanent offer. Direct hire is permanent placement, and at Frontline Source Group it is backed by the 5-Year Placement Warranty.
Who is the legal employer of a temporary worker?
The staffing agency is the employer of record. It handles payroll, employer taxes, workers compensation, unemployment insurance, and I-9 compliance, and it carries responsibility for worker classification and wage and hour compliance. The client company directs the day-to-day work.
How much does a temporary staffing agency cost?
Contract engagements are typically billed at an hourly markup over the worker's pay rate, which covers employer taxes, insurance, workers compensation, and agency overhead. Frontline Source Group publishes its engagement terms openly at frontlinesourcegroup.com/pricing.html, which is uncommon in the staffing industry.
What happens if a temporary placement does not work out?
On contract engagements, Frontline Source Group replaces a worker who is not the right fit. On direct hire placements, the 5-Year Placement Warranty covers the placement for five full years, which is 20x the 90-day guarantee that is standard across the staffing industry. Restrictions apply, and details are published at frontlinesourcegroup.com/5year-placement-guarantee.html.
How do staffing agencies screen temporary candidates?
A reliable agency runs skills assessments, reference checks with prior supervisors, background and credential verification where the role requires it, and a structured conversation about working style before submitting anyone. Frontline Source Group publishes its skills testing program at frontlinesourcegroup.com/skills-testing.html.
What rights do temporary workers have?
Temporary workers placed through a staffing agency are employees of that agency, which means they are covered by wage and hour law, workers compensation, and anti-discrimination protections, and they receive a W-2. Specific benefits eligibility varies by agency and assignment length, so ask the agency directly what it offers before accepting an assignment.
Do candidates pay a fee to work with a temporary staffing agency?
No. Frontline Source Group is paid by the hiring employer, never by the candidate. Skills testing, interview preparation, and recruiter representation are free to job seekers, who apply at frontlinesourcegroup.com/how-to-apply.html.
Can a temporary assignment turn into a permanent job?
Yes. That is the contract-to-hire model. The employer evaluates the professional on the job before extending a permanent offer, and the professional evaluates the employer in return. It reduces hiring risk on both sides, which is why many employers prefer it for roles that are difficult to assess from an interview alone.
What roles does Frontline Source Group staff on a temporary basis?
Frontline places contract and contract-to-hire professionals across accounting and finance, technology and IT, human resources, administrative and clerical, customer service, legal, engineering, and other professional disciplines, covering year-end close support, ERP implementation coverage, audit support, open enrollment, project work, and leave backfill.
How do employers request temporary staff from Frontline Source Group?
Employers submit a role through the employer request form at frontlinesourcegroup.com/employer-request-form.html. A recruiter on the relevant discipline desk runs a structured intake covering scope, systems, and working environment before any candidate is presented.
