What is a Temporary Worker?

A temporary worker is someone engaged for a limited period or a specific need — seasonal demand, covering a parental or medical leave, or a project surge — rather than being hired permanently. Temporary ("temp") workers are frequently placed by a staffing agency and carried on the agency's payroll as W-2 temps, though some are engaged as independent contractors instead. What sets them apart from permanent employees is duration and, often, who the legal employer is: the agency or a third party, not the company where the work is performed. When temp assignments stretch on indefinitely, they can create co-employment and misclassification exposure — the Vizcaino v. Microsoft "permatemp" case is the classic cautionary example — which is why many engagements follow a "temp-to-perm" conversion path.

How Temporary Work Arrangements Work

Temporary work exists to match staffing to a defined, time-bound need. An employer identifies a gap — a busy retail season, a maternity leave, a spike in project demand — and brings in a worker for the duration rather than adding a permanent headcount.

The common path

  • Agency placement (W-2 temp): A staffing agency sources the worker, puts them on its own payroll, handles taxes and withholding, and bills the client for the hours worked. The agency is the legal employer.
  • Direct contract: Some temporary needs are filled by an independent contractor or 1099 worker engaged directly, without an agency intermediary.
  • Employer of Record: A company can also hire a temp directly but route employment through an employer of record, which becomes the legal W-2 employer while the client directs the day-to-day work.

Assignments end on a set date or when the need is met. A frequent variation is temp-to-perm, where the assignment functions as an extended tryout and the worker converts to a permanent employee if the fit is right.

Key Characteristics

  • Time-bound: Engaged for a defined period or a specific need, not open-ended employment.
  • Often agency-employed: Many temps are W-2 employees of a staffing agency, which owns the payroll, tax, and benefits obligations.
  • Directed by the client: The day-to-day work is supervised by the host company even when the agency is the legal employer — the root of co-employment questions.
  • Variable classification: Most temps are W-2 employees, but some are engaged as contractors, which changes the compliance picture entirely.
  • Conversion-ready: Temp-to-perm arrangements let both sides evaluate fit before committing to a permanent hire.

The risk to watch: when a "temporary" assignment runs for months or years, the worker can start to look like a de facto employee of the host company, raising co-employment and misclassification claims.

Temporary Worker vs. Adjacent Concepts

"Temporary worker" is often used loosely to mean any non-permanent worker, but it sits inside a broader family of contingent arrangements. The distinctions matter for compliance and cost.

Worker TypeTypical Legal EmployerDurationTypical Classification
Temporary workerStaffing agency (or EoR)Limited / assignment-basedUsually W-2
Independent contractorSelf (own business)Project / SOW-based1099
Permanent employeeThe company itselfOpen-endedW-2
Gig workerSelf / platformTask-basedUsually 1099

A gig worker is typically self-employed and task-based; a consultant is engaged for expertise on a defined scope. A temporary worker is distinguished mainly by the time-bound assignment and the frequent presence of an agency as the legal employer.

Frequently Asked Questions

What is the difference between a temporary worker and an independent contractor?

The core differences are the legal employer and the classification. A temporary worker is usually a W-2 employee — most often of a staffing agency, sometimes of an employer of record — whose day-to-day work is directed by the host company. An independent contractor is self-employed, paid on a 1099 basis, and controls how the work gets done. Getting this distinction wrong is the root of most misclassification claims.

What is a "permatemp" and why is it risky?

A permatemp is a worker classified as temporary but kept on assignment for so long that they effectively function as a permanent employee. The classic case is Vizcaino v. Microsoft, where long-tenured temps successfully claimed they were owed employee benefits. Extended temp assignments raise co-employment exposure because the host company looks like a joint employer. The safest fixes are a clean EoR arrangement or a defined temp-to-perm conversion.

What does "temp-to-perm" mean?

Temp-to-perm is a hiring path where a worker starts on a temporary assignment and converts to a permanent employee if the fit is right. It functions as an extended, real-world tryout — the company evaluates performance before committing to a permanent hire, and the worker evaluates the role. It is also a practical way to limit permatemp risk by resolving open-ended assignments into a clear employment decision.

Who is the legal employer of a temporary worker?

It depends on how the engagement is structured. When a temp is placed by a staffing agency, the agency is typically the legal W-2 employer and handles payroll, taxes, and benefits. When a company hires directly through an employer of record, the EoR becomes the legal employer while the client directs the work. If the temp is engaged as a contractor, they are effectively their own employer. Because the host company usually supervises the work regardless, co-employment questions are common.
