Here’s a number that surprised us. According to the US Bureau of Labor Statistics’ most recent Contingent Worker Supplement, 54.8% of temporary staffing workers describe their own job as temporary, something they don’t expect to last. Among workers placed by contract firms, that number drops to 22.5%. Same government survey, same year, wildly different answers.
That gap is the whole reason these three terms keep getting used as if they mean the same thing when they don’t. “Contingent workforce” is the umbrella category. “Temporary staffing” and “contract staffing” are two specific, structurally different types of work that fall under that umbrella, and even the government tracks them as separate concepts on purpose.
Quick facts:
- Contingent workforce means any job without an expectation of ongoing employment. It’s a category, not a specific arrangement.
- Temporary staffing and contract staffing are two of several specific arrangements that can fall inside that category.
- BLS data shows temp agency workers are more than twice as likely as contract firm workers to describe their own job as temporary.
- “Contract staffing” gets confused with 1099 independent contractor work constantly, and they are legally very different things.
- Misclassifying a contract worker as a 1099 when they should be a W-2 employee is one of the most common and costly compliance mistakes employers make.
What Is “Contingent Workforce,” Exactly?
Contingent workforce refers to any job the worker doesn’t expect to last, regardless of how that worker is legally employed. It’s a description of job security, not a description of an employment structure.
The Bureau of Labor Statistics defines a contingent job as one with no implicit or explicit contract for ongoing employment. In July 2023, 6.9 million US workers, 4.3% of the employed population, held a job that met that definition. That’s up from 3.8% in May 2017.
Here’s the part almost every other article on this topic skips: BLS deliberately measures “contingent” and “alternative employment arrangement” as two separate things. A worker can be contingent while working a traditional in-house job (a seasonal direct hire, for example). A worker can also be in an alternative arrangement, like working through a staffing agency, without being contingent at all, if their agency job is effectively ongoing. The two concepts overlap, but neither one implies the other.
What Counts as Temporary Staffing?
Temporary staffing means a staffing agency stays the legal employer of a worker it places at a client company, usually for a defined or open-ended short-term assignment. We covered how this works in full here, so we’ll keep this part brief.
The BLS category that maps to this is “temporary help agency workers”: people paid by a temp agency, whether or not they personally consider their job temporary. In July 2023, there were 945,000 of these workers, 0.6% of total employment. And as the opening stat showed, 54.8% of them also considered their job contingent, the highest overlap of any alternative arrangement BLS tracks. In practice, most temp staffing assignments really are what they sound like: short.
What Counts as Contract Staffing?
Contract staffing means a contract firm places a worker with a single client for a defined engagement, usually longer and more skilled than a typical temp assignment, while the contract firm (not the client) generally remains the legal employer.
BLS’s closest matching category is “workers provided by contract firms,” defined as people employed by a company that provides them or their services to a single customer, usually working at that customer’s site. There were 862,000 of these workers in July 2023, 0.5% of total employment. Two things separate this group from temp staffing in the data:
- They’re less likely to see the job as temporary. Only 22.5% of contract firm workers were also contingent, less than half the rate for temp agency workers.
- They earn more. Median weekly earnings for full-time contract firm workers were $1,014, compared to $818 for temp agency workers, and closer to the $1,132 median for workers in traditional employment.
That pattern matches what shows up in practice: contract staffing skews toward higher-skill, longer-engagement work (IT, engineering, specialized project roles), while temp staffing skews toward shorter, more interchangeable assignments.
Why Do “Contract Staffing” and “1099 Contractor” Get Confused?
They get confused because both involve the word “contract,” but they’re legally different categories, and mixing them up is one of the most common and expensive compliance mistakes an employer can make.
Contract staffing usually means a W-2 arrangement. The worker is a legal employee of the contract firm, which withholds taxes and typically provides some benefits, even though they work at the client’s site under the client’s day-to-day direction.
1099 independent contractor work means the worker is self-employed. No one withholds taxes on their behalf, and by IRS rule, the business paying them can only control the outcome of the work, not how or when it gets done.
The IRS is direct about why this distinction matters: if a business treats someone as a 1099 contractor when the actual working relationship looks like employment, that’s misclassification, and it can trigger back taxes and penalties regardless of what the contract paperwork says the relationship is. The label on the agreement doesn’t decide the classification. The actual level of control does.
This is also an active regulatory area. In addition to the joint employer rulemaking we covered in our temp staffing vs. RPO comparison, the Department of Labor’s April 2026 proposed rule specifically addresses independent contractor classification alongside joint employer status. Worth checking current status before relying on any specific guidance here, since this is still evolving.
How Do the Three Actually Compare?
Here’s the BLS data side by side. This is the most direct, current picture of how these arrangements actually differ in practice, not just in theory.
| Temporary Staffing | Contract Staffing | 1099 Independent Contractor | |
|---|---|---|---|
| US workers (July 2023) | 945,000 (0.6% of employment) | 862,000 (0.5% of employment) | 11.9 million (7.4% of employment) |
| Also considered “contingent” | 54.8% | 22.5% | 4.1% |
| Median weekly earnings, full-time | $818 | $1,014 | $949 |
| Any health insurance coverage | 60.8% | 79.4% | 74.2% |
| Prefers this arrangement over a traditional job | 48.2% | not tracked by BLS | 80.3% |
| Typical legal employer | Staffing agency (W-2) | Contract firm (usually W-2) | The worker themselves (self-employed) |
A few things stand out here. Independent contractors are, by far, the largest group and the most satisfied with their arrangement, largely because most of them chose self-employment on purpose. Temp agency workers earn the least and are the least likely to have health coverage, consistent with the short-term nature of most assignments. Contract staffing sits in between on almost every measure, which tracks with it usually involving longer, more specialized engagements than temp staffing.
Which Term Should Guide Your Workforce Strategy?
The right term depends on what you actually need: a short-term fill, a defined specialized engagement, or a role you’ll want to keep filled indefinitely.
- Need someone for a few days to a few months, for work that doesn’t require specialized skill? That’s temporary staffing.
- Need a skilled specialist for a defined project, and you’re comfortable with the contract firm holding the employment relationship? That’s contract staffing.
- Considering hiring someone as a 1099 contractor to save on payroll costs? Check the actual working relationship against the IRS test first. If you’ll control their schedule, tools, or day-to-day process, that’s an employee, not a contractor, no matter what the agreement says.
- Realize the role isn’t actually temporary at all? That’s usually the point where RPO becomes the better fit, since it makes the worker your direct employee from day one and sidesteps the classification question entirely.
Frequently Asked Questions
Is “contract staffing” the same as being a 1099 independent contractor?
No. Contract staffing usually means the worker is a W-2 employee of a contract firm that places them with a client. A 1099 independent contractor is self-employed and isn’t an employee of anyone. Confusing the two is a common and costly compliance mistake.
What’s the difference between temporary staffing and contract staffing?
Temporary staffing tends to be shorter, lower-skill, and more likely to end on schedule. Contract staffing tends to run longer, pay more, and involve more specialized work. BLS data shows temp agency workers are more than twice as likely to consider their job temporary as contract firm workers are.
Is contingent workforce the same thing as temp staffing?
No. Contingent workforce is the broader category, any job the worker doesn’t expect to last. Temp staffing is one specific type of arrangement that often, but not always, falls into that category.
Can a contract worker be misclassified?
Yes, and it’s one of the more common compliance failures in this space. Misclassification happens when a business treats someone as a 1099 contractor while actually controlling their schedule, tools, or work process the way it would for an employee.
Do contract staffing workers get benefits?
Often, more so than temp staffing workers. BLS data shows 79.4% of contract firm workers have some form of health insurance coverage, compared to 60.8% of temp agency workers.
What percentage of the US workforce is contingent?
4.3% as of July 2023, according to BLS, up from 3.8% in 2017. That’s 6.9 million workers whose main job doesn’t come with an expectation of ongoing employment.
Is an RPO hire considered a contingent workforce?
No. RPO places a permanent, direct employee of the client company. There’s no expectation the role will end, so it doesn’t meet the definition of contingent or fall into any of BLS’s alternative arrangement categories.
Which arrangement has the least compliance risk?
Direct employment through RPO, since there’s no third-party employer or contractor classification question to get wrong. Between temp and contract staffing, risk mostly comes down to how much day-to-day control the client exercises over the worker, not which label is used.
