For decades, Fair Labor Standards Act collective actions had a familiar rhythm: file the lawsuit, ask for “conditional certification,” send notice to a broad group of employees, gather opt-ins, conduct discovery, and then fight later about whether the group really belonged together. It was the litigation equivalent of inviting the whole neighborhood to dinner and checking afterward whether anyone actually knew the host.
Then the U.S. Court of Appeals for the Fifth Circuit stepped in with Swales v. KLLM Transport Services, L.L.C., a major wage-and-hour decision that rejected the widely used two-step approach for certifying FLSA collective actions. Instead of allowing notice based on a light early showing, the Fifth Circuit told district courts to determineearly and carefullywhether the proposed opt-in plaintiffs are actually “similarly situated.”
The decision reshaped FLSA litigation in Texas, Louisiana, and Mississippi, and it continues to influence national debates about collective action certification, employee notice, settlement pressure, and the proper role of courts in wage-and-hour lawsuits.
What Is an FLSA Collective Action?
The Fair Labor Standards Act, commonly called the FLSA, is the federal law that sets core wage protections such as minimum wage and overtime pay. Covered nonexempt employees generally must receive overtime pay at one and one-half times their regular rate for hours worked over 40 in a workweek.
When employees believe an employer has violated the FLSA, they may bring claims individually. They may also sue on behalf of themselves and other employees who are “similarly situated.” This is called a collective action under Section 216(b) of the FLSA.
Collective Actions Are Not the Same as Rule 23 Class Actions
A common mistake is treating FLSA collective actions like traditional class actions. They are cousins, not twins. In a Rule 23 class action, eligible class members are generally included unless they opt out. In an FLSA collective action, workers must affirmatively opt in by filing written consent with the court.
That opt-in requirement matters. A worker does not become part of the lawsuit simply because a court approves notice. The worker must choose to join. Still, court-approved notice can dramatically expand a case by alerting dozens, hundreds, or even thousands of potential plaintiffs.
The Old Two-Step Approach: The Lusardi Framework
Before Swales, many courts used a two-step framework often called the Lusardi approach, named after a 1987 district court decision. Although the FLSA itself does not use the phrase “conditional certification,” that phrase became standard in wage-and-hour litigation.
Step One: Conditional Certification
At the first stage, the plaintiff asked the court to conditionally certify a proposed collective and authorize notice to potential opt-in plaintiffs. Courts often applied a lenient standard, requiring only a modest factual showing that the named plaintiff and proposed group were similarly situated.
In practice, this early stage could rely heavily on pleadings, declarations, or limited evidence. Employers often argued that the first step was too easy to satisfy and that notices were being sent to employees who might not share the same job duties, pay practices, defenses, arbitration agreements, or factual circumstances.
Step Two: Decertification
After notice went out and workers opted in, the parties conducted discovery. Later, usually after discovery closed, the employer could move to decertify the collective. At that point, the court conducted a more demanding review of whether the opt-in plaintiffs were actually similarly situated.
If the court decertified the collective, the opt-in plaintiffs could be dismissed without prejudice, leaving the named plaintiff to proceed alone. That sounds tidy on paper. In real litigation, however, the case may already have become expensive, complicated, and settlement-heavy by then.
What Happened in Swales v. KLLM Transport Services?
Swales involved truck drivers who sued KLLM Transport Services under the FLSA. They alleged that KLLM misclassified drivers as independent contractors rather than employees, affecting wage obligations. The plaintiffs sought conditional certification so that notice could be sent to other drivers.
The district court applied a version of the Lusardi two-step approach and granted conditional certification. But the Fifth Circuit vacated that order and remanded the case. The appellate court said the Lusardi framework lacked a firm anchor in the FLSA’s text or Supreme Court precedent.
The Fifth Circuit emphasized a simple but powerful point: the FLSA says employees may proceed collectively only if they are “similarly situated,” but it does not mention “certification” or “conditional certification.” In the court’s view, district courts should not use a judge-made shortcut that allows notice before the similarity question has been meaningfully tested.
The Fifth Circuit’s New Rule: Scrutinize Similarity Early
The key lesson from Swales is that district courts must rigorously scrutinize whether proposed opt-in plaintiffs are similarly situated at the outset of the case. Instead of applying a lenient first-stage test, courts should identify the facts and legal issues that matter to the similarity question and allow preliminary discovery tailored to those issues.
What “Similarly Situated” Means After Swales
The phrase “similarly situated” is not precisely defined in the FLSA. After Swales, courts in the Fifth Circuit must look closely at whether the proposed group shares material similarities relevant to the claims and defenses. That may include job duties, pay policies, classification decisions, timekeeping practices, compensation structures, arbitration agreements, geographic differences, and individualized factual disputes.
For example, if all employees were subject to the same automatic meal-break deduction policy, similarity may be easier to show. But if the claim turns on individualized decisions by different managers across different worksites, the court may require more evidence before notice goes out.
Preliminary Discovery Becomes More Important
Under the Fifth Circuit’s approach, preliminary discovery is not a side dish; it is part of the main course. The district court should decide what information is needed to test similarity before authorizing notice. In some cases, that discovery may be narrow. In others, it may be extensive.
This means both sides must be ready earlier. Plaintiffs need evidence showing that the proposed collective is tied together by a common policy or practice. Employers need evidence showing meaningful differences among employees, defenses, or work arrangements. The court then decides whether notice should issue, and to whom.
Why the Fifth Circuit Rejected Lusardi
The Fifth Circuit’s reasoning was rooted in statutory text, judicial neutrality, and litigation fairness. The court did not say collective actions are improper. Far from it. The FLSA expressly allows similarly situated employees to proceed together. But the court objected to sending notice before determining whether the recipients are actually similar to the named plaintiffs.
1. The FLSA Does Not Mention Conditional Certification
The court focused on the statute’s actual language. Section 216(b) allows employees to sue for themselves and other employees “similarly situated.” It also requires written consent for an employee to become a party plaintiff. But it does not create a two-step certification process.
That absence mattered. The Fifth Circuit concluded that courts should not treat conditional certification as though it were written into the statute when Congress did not put it there.
2. Court-Approved Notice Can Create Settlement Pressure
Once notice is sent, a case can grow quickly. More opt-ins can mean broader discovery, larger potential damages, higher attorney’s fees, and greater pressure to settle. The Fifth Circuit worried that a lenient first step could allow weak or overbroad collectives to gain leverage before the court has tested whether the workers truly belong together.
In plain English: notice is not just a postcard. It can change the economics of the lawsuit.
3. Courts Must Avoid Appearing to Endorse the Merits
The Supreme Court has recognized that district courts may facilitate notice in collective actions for case-management purposes. But courts must remain neutral and avoid even the appearance of endorsing the merits of the case. The Fifth Circuit viewed early, lightly tested notice as risky because recipients may interpret a court-authorized notice as a signal that the claim has judicial approval.
How Swales Changes Strategy for Plaintiffs
For plaintiffs, Swales raises the front-end burden. A complaint with broad allegations and a few declarations may not be enough. Plaintiffs must think earlier about evidence, not just storytelling.
Plaintiffs Should Build a Stronger Early Record
Effective plaintiff strategy after Swales often includes identifying a specific unlawful policy, gathering declarations from multiple employees, showing common job duties, and explaining why defenses will not overwhelm the collective. Plaintiffs may also seek targeted discovery before notice, such as pay policies, job descriptions, time records, classification documents, and organizational charts.
The better the early record, the easier it is to show the court that notice should go to a defined group of truly similar workersnot a crowd assembled with a fishing net.
How Swales Changes Strategy for Employers
For employers, Swales creates an earlier opportunity to challenge the proposed collective. Employers no longer need to wait until the decertification stage to argue that the group is too diverse, too individualized, or too dependent on employee-specific facts.
Employers Should Prepare Early Opposition Evidence
Employers may focus on differences in job duties, locations, supervisors, schedules, compensation methods, exempt status analyses, arbitration agreements, or independent contractor relationships. If the proposed group includes workers with different agreements, different duties, or different legal defenses, those distinctions may matter before notice is approved.
In other words, the defense does not have to sit politely in the back row until step two. Under Swales, it gets a microphone much earlier.
Examples of How the Swales Standard May Apply
Example 1: Uniform Overtime Policy
Suppose a company has a written policy requiring all hourly warehouse employees nationwide to perform 15 minutes of unpaid pre-shift work every day. If the named plaintiff can show that the same policy applied to the proposed group, the court may find that the employees are similarly situated.
Example 2: Highly Individualized Misclassification Claim
Now imagine a company classifies various managers as exempt, but their duties differ widely by store, region, supervisor, and business unit. Some managers spend most of their time supervising; others mostly stock shelves. In that situation, the employer may argue that the similarity question requires individualized analysis and that broad notice is inappropriate.
Example 3: Independent Contractor Drivers
In a driver misclassification case, the court may examine whether drivers signed the same agreements, used similar routes, controlled their schedules, owned equipment, hired helpers, or operated under materially different business arrangements. A shared job title alone may not be enough.
Impact Beyond the Fifth Circuit
The Fifth Circuit directly controls federal courts in Texas, Louisiana, and Mississippi. But Swales has had a national ripple effect. The Sixth Circuit later rejected the traditional two-step approach and adopted a “strong likelihood” standard before notice. More recently, the Seventh Circuit also moved away from the old lenient approach, adopting a more flexible framework that gives employers an opportunity to rebut similarity evidence before notice is issued.
Not every circuit has followed Swales. Some courts still use versions of the Lusardi framework. That means FLSA certification strategy can vary dramatically depending on where the lawsuit is filed. For national employers, this creates a patchwork of procedural rules. For plaintiffs, venue can influence how quickly notice may be sent and how much evidence is needed upfront.
What the Decision Means for Wage-and-Hour Litigation
Swales did not eliminate FLSA collective actions. It changed the gatekeeping process. The decision demands earlier clarity about who belongs in the case and why. That can reduce overbroad notices, but it can also increase early litigation costs because parties may fight harder over preliminary discovery and similarity evidence.
The ruling also encourages sharper collective definitions. Instead of proposing “all employees who worked for the company during the last three years,” plaintiffs may need narrower groups tied to specific job titles, locations, policies, or pay practices. Employers, meanwhile, must preserve and present evidence that helps courts understand whether differences among workers are legally meaningful.
Practical Experience and Lessons From FLSA Collective Action Disputes
In practical wage-and-hour litigation, the certification fight often becomes the moment when a case’s true shape finally appears. At the pleading stage, a proposed collective can look simple: same employer, same job title, same alleged pay problem. But once records, declarations, agreements, and worksite practices enter the picture, the neat little box may start sprouting antennas.
One common experience in FLSA cases is that job titles can be misleading. Two employees may both be called “assistant managers,” but one may supervise teams, control schedules, discipline employees, and exercise discretion, while another may spend nearly every shift running a register. Under a lenient two-step model, both might receive notice early. Under the Swales approach, the court is more likely to ask whether those differences matter before expanding the case.
Another practical lesson is that written policies are powerful, but they are not always the whole story. A uniform handbook may say employees must record all hours worked. Plaintiffs may respond that managers unofficially discouraged overtime reporting. Employers may counter that practices varied by location or supervisor. The court then has to decide whether the alleged unlawful practice is common enough to support collective treatment or too individualized to justify broad notice.
Timing is also a major issue. Plaintiffs want notice sent quickly because the FLSA statute of limitations continues to run for potential opt-in plaintiffs until they file consent. Delay can shrink claims. Employers, however, want courts to test the proposed collective before notice creates pressure and expense. Swales shifts more of that battle to the beginning of the case, where the court must balance speed, fairness, and accuracy.
For plaintiffs’ counsel, the experience-based lesson is simple: prepare before filing as though the certification fight starts on day onebecause in the Fifth Circuit, it does. Strong declarations, clear policy evidence, and a carefully defined collective can make the difference between targeted notice and no notice at all.
For defense counsel, the lesson is equally clear: do not wait for decertification. Gather employee-specific facts early. Identify variations in duties, pay plans, locations, supervision, contracts, arbitration agreements, and timekeeping practices. The earlier those differences are shown, the more effectively an employer can challenge overbroad notice.
For employers outside litigation, Swales offers a compliance reminder. Consistent pay practices, accurate records, clear classifications, and well-trained managers are not just HR housekeeping. They are litigation armor. When wage policies are documented and applied consistently, employers are better positioned to defend similarity questions. When practices vary informally, litigation becomes messier, costlier, and about as pleasant as finding a stapler in the office microwave.
Conclusion
The Fifth Circuit’s rejection of the two-step approach in Swales v. KLLM Transport Services marked a turning point in FLSA collective action litigation. By rejecting Lusardi’s lenient conditional certification model, the court required district judges to examine the “similarly situated” issue earlier and more rigorously.
For plaintiffs, the decision means stronger evidence is needed sooner. For employers, it creates an earlier opportunity to challenge overbroad collectives. For courts, it reframes notice as a careful case-management tool rather than a near-automatic first step.
The big takeaway is this: in the Fifth Circuit, FLSA notice is no longer a warm-up act. It is a serious judicial decision that requires real evidence, real analysis, and a real connection among the employees who seek to proceed together.
