Contingent hiring has become an important part of workforce planning for companies that need specialized skills, project-based support, or additional capacity without adding every role as a permanent position. Older workforce forecasts suggested that the U.S job market will consist at least 50% of contingent workforce by 2050. Rather than treating that long-range projection as a current measure, employers can look to official U.S. Bureau of Labor Statistics data: in July 2023, 4.3% of workers held contingent jobs in their sole or main job, while 7.4% were independent contractors.

Earlier Statista projections also highlighted the rapid growth of the gig economy and digital freelance platforms. Although those specific forecasts are now historical, the underlying hiring challenge remains relevant: companies need a reliable way to source, assess, engage, and manage workers across different employment arrangements.

1. What is Contingent Hiring?

Contingent hiring is the process of engaging workers for a defined period, project, assignment, or business need rather than automatically hiring them as long-term employees. A contingent workforce can include temporary workers, independent contractors, consultants, freelancers, on-call workers, and workers supplied through staffing or contract firms, depending on the arrangement.

For example, a company may engage an IT developer for a specific implementation project, bring in temporary customer-support staff during a demand spike, or use a specialist consultant for work that requires expertise not available internally.

Matt Erhard, Managing Partner at Summit Search Group, has emphasized the value of maintaining long-term relationships with contractors and temporary workers while recognizing that quality and consistency can be harder to manage than with permanent staff. That balance is central to an effective contingent workforce strategy.

2. How Can Companies Benefit from Contingent Hiring?

• Access specialized talent for defined projects, tasks, or assignments without creating a permanent role for every short-term need.
• Increase workforce flexibility during busy periods, seasonal demand, product launches, transformations, or temporary staffing gaps.
• Scale teams up or down more quickly when business requirements change.
• Gain access to experienced specialists who can contribute quickly when the required knowledge is not available in-house.
• Use different talent channels to support project delivery while protecting permanent teams from unnecessary workload pressure.

Tax and payroll treatment should not be viewed as an automatic benefit of contingent hiring. In the United States, responsibilities depend on the worker’s correct classification. The IRS advises businesses to evaluate behavioral control, financial control, and the nature of the working relationship when determining whether someone is an employee or an independent contractor.

3. What Are the Drawbacks of Contingent Workers?

• Commitment and continuity can be harder to maintain when workers are engaged only for a limited project or period.
• Frequent worker turnover can create operational, knowledge-transfer, and security risks, particularly when contingent workers handle sensitive or confidential information.
• Consistency may be more difficult when teams repeatedly onboard new temporary workers or use multiple staffing suppliers.
• Misclassification can create legal, tax, and compliance risk if a worker is treated as an independent contractor when the working relationship functions like employment.
• Temporary workers may have less context about company processes, culture, customers, and internal systems unless onboarding and communication are handled well.

4. How to Hone a Contingent Worker’s Skills and Expertise

Employers sometimes focus mainly on general soft skills when hiring temporary or contract workers. However, contingent hiring is more effective when candidates are evaluated against the specific knowledge, technical skills, and job requirements needed for the assignment.

Companies can strengthen contingent worker quality through the following practices:

• Accurate job description that clearly defines responsibilities, required skills, project scope, deliverables, and expectations.
• Recruiting tools such as applicant tracking systems, candidate-engagement tools, and structured screening workflows.
• Assess specific skills and knowledge to identify workers who can perform the required tasks, not just candidates with relevant titles on a resume.
• Asynchronous video interviews to evaluate communication and role-specific responses beyond the CV.
• Ask for referrals or references from past clients or employers when appropriate for the role and hiring process.
• Verify the candidate’s job history when verification is relevant and permitted by applicable hiring and privacy requirements.
• Use an onboarding process that explains the project, communication channels, security requirements, company policies, and success measures.

Talent-quality platforms such as Glider AI can support contingent recruiting through screening, skills assessments, interviews, and candidate-evaluation workflows. For contingent roles, the objective is to verify whether the worker can perform the assignment successfully before the hiring team invests heavily in later-stage interviews or onboarding.

5. How to Avoid Common Mistakes in Contingent Hiring

Employers should avoid major mistakes when hiring contingent workers, particularly the assumption that temporary workers require less management simply because their engagement is limited. Managers still need to set expectations, answer questions, provide relevant feedback, and make sure workers have what they need to deliver quality work.

Clear and frequent communication should be a priority without turning into micromanagement. Contingent workers may work under different arrangements from permanent employees, but they still need clarity about responsibilities, deadlines, decision-makers, security procedures, and how their work connects to the wider project.

A strong onboarding experience is equally important. It should cover the information a worker needs to become productive quickly, including company policies that apply to the engagement, tools and systems, project expectations, communication norms, and escalation paths.

Frequently Asked Questions

What is contingent hiring?

Contingent hiring is the process of engaging workers for a temporary, project-based, contract, freelance, on-call, or other defined workforce need rather than automatically filling the requirement with a permanent employee.

What is the difference between a contingent worker and a permanent employee?

A permanent employee is generally hired for an ongoing employment relationship, while a contingent worker is typically engaged for a defined period, assignment, project, or business need. The exact legal and tax classification depends on the facts of the working relationship and applicable law.

What are the main benefits of contingent hiring?

Common benefits include workforce flexibility, access to specialized skills, support during peak demand, faster scaling for project needs, and the ability to supplement permanent teams for defined assignments.

What are the risks of contingent hiring?

Potential risks include worker misclassification, inconsistent quality, higher turnover, knowledge loss, data-security concerns, weak onboarding, and poor communication if the contingent workforce is not managed carefully.

How can companies improve contingent worker quality?

Companies can improve quality by using clear job descriptions, structured screening, job-relevant skills assessments, interviews, reference or employment verification when appropriate, and effective onboarding with clear performance expectations.

Conclusion

Contingent hiring can give companies access to specialized skills and workforce flexibility, but strong results depend on more than finding people who are available. Employers need clear role requirements, reliable candidate evaluation, correct worker classification, consistent communication, and effective onboarding. When these practices are built into the contingent hiring process, companies can respond to changing workforce needs while maintaining talent quality and reducing avoidable risk.
