Does Kelly Services Drug Test?

Drug Testing by Position

Drug Testing at Kelly Services Depends on the Client

Kelly Services is a staffing agency, not a direct employer for most of the people it places. When you work through Kelly, you are assigned to a client company's worksite. The drug testing requirement comes from the client, not from Kelly itself. Many industrial, manufacturing, and warehouse clients require pre-assignment drug testing as part of their workplace safety programs. Some office and professional clients also require testing, though this is less common. When you apply for an assignment through Kelly, you will be informed whether drug testing is required for that specific placement.

Industrial and Warehouse Assignments — Usually Tested

If you are seeking a warehouse, manufacturing, or industrial placement through Kelly Services, expect to be drug tested. These clients operate in environments with heavy machinery, forklifts, and other safety-sensitive equipment, and drug testing is a standard safety requirement. The test is typically a urine drug screen conducted at a third-party collection site before your first day at the client site. Some industrial clients also require ongoing random testing or post-accident testing during the assignment.

Office and Professional Assignments — Less Likely

Office, clerical, administrative, and many professional assignments placed through Kelly Services are less likely to require drug testing. These positions are generally not considered safety-sensitive, and many office-based client companies have moved away from pre-employment drug testing. However, some clients — particularly in regulated industries like healthcare, finance, and government — may still require testing for all workers, including temporary staff. Always ask your Kelly recruiter about specific requirements for your assignment.

Frequently Asked Questions

Does Kelly Services drug test all temp workers?

No. Kelly Services does not drug test all temporary workers. Drug testing requirements are determined by the client company you are being placed with. Warehouse, manufacturing, and industrial clients typically require testing, while office and clerical clients may not. Your Kelly recruiter will inform you if testing is required for your specific assignment.

What type of drug test does Kelly Services use?

When drug testing is required, Kelly Services typically uses a urine drug test (urinalysis). Some clients may use oral fluid (mouth swab) tests instead. The standard panel screens for marijuana (THC), cocaine, amphetamines, opiates, and PCP. The specific panel depends on the client's requirements.

Can I decline an assignment that requires drug testing?

Yes. If an assignment requires drug testing and you prefer not to be tested, you can decline that assignment and ask your Kelly recruiter about other available positions that do not require testing. Office and clerical assignments are less likely to require drug testing.

Does Kelly test for marijuana?

It depends on the client. Some Kelly clients still include marijuana (THC) in their drug testing panels, while others — particularly in states with legal recreational marijuana — have removed it. In states that prohibit pre-employment marijuana testing for non-safety-sensitive positions, the law applies regardless of whether you are a temporary or permanent employee.

What happens if I fail a drug test through Kelly Services?

If you fail a drug test for a specific assignment, that assignment will be withdrawn. Depending on Kelly's policies and the circumstances, you may still be eligible for other assignments that do not require drug testing. However, the failed test may be noted in your Kelly Services file and could affect future placements with clients that require testing.
