What does DNR (do not return) mean in staffing? The client request, the worker, and the process

In staffing, DNR stands for "do not return": a client's instruction that a particular temporary worker should not be sent back to that client's site. It ends that worker's assignment with that client; it does not, on its own, end the worker's employment with the agency or bar them from other clients, which is a separate decision the agency makes. Because the agency acts on the request, it also shares the risk if the reason is discriminatory or retaliatory: the EEOC has said a staffing firm "must take immediate and appropriate corrective action if it learns that its client has discriminated against one of the staffing firm's employees" (EEOC, 1997, still cited as of October 2026).

Our rehire eligibility policy template covers an employer's own rehire codes, and the contractor offboarding checklist covers the end of an assignment. A DNR is different: the request comes from the client, about a worker who is usually the agency's employee.

What does a DNR mean for the worker?

Agencies use other labels for the same thing ("do not send", "do not refer", "client restricted"). Whatever the label, keep two records apart: the client's request, and the agency's own decision about the worker. A worker removed for a conflict with one supervisor may be an excellent redeployment candidate elsewhere; see redeployment rate.

Why do clients make DNR requests?

• Attendance: no-shows, lateness, leaving early.
• Performance: errors, speed below the standard, not following instructions.
• Safety: ignoring procedures or protective equipment rules.
• Conduct: policy breaches, conflict, misuse of systems or property.
• "Not a good fit": the most common and least useful reason. Ask what happened.

Some reasons are red flags that need review before the agency acts on the request:

• The reason mentions or hints at race, color, religion, sex (including pregnancy), national origin, accent, age, disability, a medical condition or another characteristic protected by federal, state or local law.
• The request follows the worker raising a complaint: harassment, discrimination, pay, safety or an injury.
• The request follows a request for an accommodation, leave or a schedule change for religious reasons.
• The client asks for "someone different" in a way that describes a demographic rather than a skill.

What does the law say about acting on a client's request?

Several federal rules apply directly to staffing firms. This is general information as of October 2026, not legal advice; state and local laws add more.

• Referral and classification: Title VII makes it unlawful "for an employment agency to fail or refuse to refer for employment, or otherwise to discriminate against, any individual because of his race, color, religion, sex, or national origin, or to classify or refer for employment any individual on the basis of" those characteristics (42 U.S.C. 2000e-2(b)). A DNR flag is a classification; it needs a lawful reason behind it.
• Joint responsibility: the EEOC's 1997 announcement of its contingent worker guidance says these workers "typically qualify as 'employees' of the staffing firm, the client to whom they are assigned, or both". Its later ADA guidance for staffing firms summarizes that either may be liable for the other's discrimination if it "participates in the discrimination" or "knew or should have known of the discrimination and failed to take corrective action within its control".
• What corrective action looks like: in one example in that ADA guidance, a client refused a temp who could not drive because of epilepsy, for a job where driving was not required. The EEOC said the staffing firm "should offer CP the next available position for which he is qualified, inform XYZ of its ADA obligations, and should not assign other workers to XYZ until it agrees to abide by these obligations."
• Retaliation: Title VII also bars an employment agency from discriminating against anyone "because he has opposed any practice made an unlawful employment practice" or made a charge or took part in an investigation (42 U.S.C. 2000e-3(a)). A DNR that follows a complaint needs a close look at the timing and the documented reason.

Who counts as the employer for wage-and-hour and labor-law purposes is covered in joint employer liability for staffing agencies, and a DNR that follows a safety complaint raises the issues in OSHA's temporary worker rules.

How should an agency handle a DNR request?

1. Get it in writing from an authorized client contact: worker, assignment, date, who is asking. A phone call is fine as a start; follow it with an email that confirms what was said.
2. Ask for the facts. Dates, incidents, the rule or standard involved, any warnings given. "Not a fit" becomes "missed the rate standard on five of eight shifts" or it stays vague, which is itself worth recording.
3. Hear the worker. Ask for their account before closing the record. It may reveal a complaint, an injury or an accommodation request the client did not mention.
4. Screen for red flags using the list above. If any apply, escalate to HR or counsel before agreeing to anything beyond removing the worker from the site.
5. Decide the scope separately. Client-only restriction, agency-wide review, or (for serious verified misconduct) an agency decision on continued employment under your own policy.
6. Tell the worker (see below), and confirm final hours and pay.
7. Record the flag in the applicant tracking system with a reason code, the facts, the decision and a review date.
8. Redeploy if the worker remains eligible.

How should DNR flags work in the ATS?

DNR RECORD
Worker: [ID]          Client: [name / site]      Assignment: [order ID]
Requested by: [name, title]   Date: [ ]   Received: [email / call + email]
Reason category: attendance | performance | safety | conduct | other
Facts given: [dates, incidents, standard]   Worker's account: [ ]
Red-flag review: none found | escalated to [name] on [date]
Decision: client-only restriction | agency review | not eligible for rehire
Decided by: [name]   Review date: [ ]   Visible to: [roles]

• Make the flag client-specific by default, so a restriction at one site does not silently hide the worker from every recruiter.
• Use reason categories, and keep notes factual. Never record protected characteristics as a reason.
• Limit who can see the notes, and review flags on the set date rather than keeping them forever.
• Report DNRs by client. A client that issues far more DNRs than others is a training, supervision or expectations problem worth raising at the next review.

What should you say to the worker?

"[Name], [client] has ended your assignment and asked that we don't send
you back to that site. The reason they gave is [factual reason, e.g. three
late starts in two weeks]. I'd like to hear your side before I note it.

This applies to [client] only. You're still [eligible for other
assignments / under review], and I'll [call you by Thursday about
openings / let you know by date]. Your hours through [last shift] will be
paid on the normal payday. If you think the reason is unfair or connected
to something you raised there, tell me now or contact [HR contact]."

Do not repeat the client's opinions word for word if they are unverified or insulting, and do not promise that the decision will be reversed.

What should the client agreement say?

• DNR requests in writing, with a reason and the facts behind it.
• No requests based on characteristics protected by law, and a commitment from the client to the same anti-discrimination and anti-retaliation standards the agency follows.
• Who pays for the hours already worked, and any replacement terms. Some public contracts set this; for example, Sedgwick County, Kansas' 2026 temporary medical staffing RFP required agencies not to charge for a temp terminated within the first three days (see how to respond to a staffing RFP).
• How the client reports performance problems before they become a DNR, so the agency can coach first.

The agency client onboarding checklist is the place to agree this before the first order, and a clear assignment confirmation email setting out the site's rules prevents some DNRs entirely.
