Hybrid Salary + Day-Rate Pay Is “Salary-Basis” Under 29 C.F.R. § 541.602(a) When a Predetermined Weekly (or Less Frequent) Guarantee Exists—No § 541.604(b) Reasonable-Relationship Test

I. Introduction

Guilbeau v. Schlumberger Technology is a Fair Labor Standards Act (“FLSA”) collective action dispute over overtime eligibility for oilfield personnel paid under a “hybrid” scheme: a fixed biweekly amount plus variable day-rate payments and bonuses. The plaintiffs—Trever Guilbeau (Directional Driller) and Christopher O’Mara (Measuring While Drilling)—alleged they routinely worked more than 40 hours per week without overtime compensation and sought relief for themselves and similarly situated workers.

Schlumberger moved for partial summary judgment as to Guilbeau, arguing he was exempt as a “highly compensated employee” (“HCE”) and, critically, that he was paid on a “salary basis.” The district court denied summary judgment but certified an interlocutory appeal under 28 U.S.C. § 1292(b), citing a shifting legal landscape. The Fifth Circuit reversed, holding Guilbeau’s pay satisfied the salary-basis requirement under the governing regulation.

Key issue presented

• Whether a pay plan with (i) a guaranteed, fixed biweekly amount not reduced for quantity/quality of work and (ii) substantial day-rate compensation is governed by 29 C.F.R. § 541.602(a) (salary basis) or by 29 C.F.R. § 541.604(b) (daily/hourly/shift computation with a “reasonable relationship” requirement).

II. Summary of the Opinion

The Fifth Circuit held that Guilbeau was paid on a salary basis under 29 C.F.R. § 541.602(a) because he “regularly receive[d]” each pay period a predetermined amount (the biweekly $1,826) that constituted “all or part” of his compensation and was not subject to reduction based on work variations. The court treated the day-rate and bonus amounts as permissible additional compensation under 29 C.F.R. § 541.604(a), which does not defeat salary-basis status so long as a qualifying guarantee exists.

Because the parties disputed only the salary-basis prerequisite to the HCE exemption—and Guilbeau otherwise met the exemption criteria—the court ordered summary judgment for Schlumberger on Guilbeau’s claim. The court remanded for further proceedings concerning the opt-in collective members, emphasizing that the record did not establish their individualized exemption elements (duties, compensation thresholds, etc.).

III. Analysis

A. Precedents Cited

1. Collective action procedure and case posture

• Swales v. KLLM Transp. Servs. — Cited to distinguish FLSA collective actions from Rule 23 class actions and to frame the “opt-in mechanism.” While not determinative of the exemption issue, it contextualizes why notice/collective management can become complex once a named plaintiff’s claim is resolved.
• Smith v. Ochsner Health Sys. — Provides the de novo standard for reviewing denial of summary judgment and reiterates the employer’s burden on exemptions; the court used it to set the standard of review and allocation of proof.
• Icicle Seafoods, Inc. v. Worthington — Cited (via Smith) for the proposition that exemption status is a question of law, while how an employee spends working time is a question of fact—important to the remand decision regarding opt-in members whose duties and compensation records were not established.
• Owsley v. San Antonio Indep. Sch. Dist. — Reinforces the employer’s burden to prove an exemption.
• Castellanos-Contreras v. Decatur Hotels, LLC — Supports limiting interlocutory review to the issue fairly raised by the appealed orders; the panel therefore declined to reach estoppel and notice-process disputes.

2. Salary-basis doctrine and the Helix framework

• Hewitt v. Helix Energy Sols. Grp., Inc. (en banc), aff'd, Helix, 598 U.S. 39 (2023) — The centerpiece authority for parsing the salary-basis regulations. The panel relied on Helix’s textual emphasis that:
  • § 541.602(a) concerns a predetermined sum paid weekly or less frequently.
  • § 541.604(b) is aimed at compensation “computed on an hourly, a daily or a shift basis” and adds the “reasonable relationship” test.
  • “Basis” refers to the method for calculating pay, not merely the frequency of distribution—critical to identifying which regulatory pathway controls.

3. Fifth Circuit’s recent pay-scheme taxonomy: Venable and Gentry

• Venable v. Smith International — Treated by the panel as essentially controlling. Venable involved a “bifurcated” oilfield pay structure: an annual salary paid bi-weekly plus daily-rate pay for rig services. The Fifth Circuit there rejected the argument that day-rate additions converted the plan into a § 541.604(b) daily computation. The panel applied Venable’s logic directly: if the guaranteed salary is independent of time worked, meets the minimum weekly threshold, and is calculated weekly or longer, then § 541.602(a) governs and day-rate add-ons do not defeat exempt status.
• Gentry v. Hamilton-Ryker IT Sols., L.L.C. — Used to illustrate the opposite scenario: workers paid hourly with only an “illusory” guarantee (eight hours of wages per week) valued by multiplying an hourly rate by hours. Gentry reinforced that the “basis” of the purported salary determines the governing test; because the guarantee was fundamentally hourly, it did not satisfy § 541.602(a). The panel contrasted Guilbeau: his guaranteed amount was a fixed biweekly lump sum, not an hourly-derived backstop.
• Hebert v. FMC Techs., Inc. (unpublished) — Cited as consistent Fifth Circuit treatment of similar oilfield hybrid compensation: an admitted biweekly salary not tied to hours/days is “plainly” salary-basis under § 541.602(a).

4. Sister-circuit alignment

• Wilson v. Schlumberger Tech. Corp. — Notable because it addressed “this very same pay system” for Schlumberger MWDs. The Tenth Circuit, like the Fifth here, treated the hybrid plan as governed by § 541.602(a), not § 541.604(b).
• Bell v. Callaway Partners, LLC (unpublished) and Hogan v. Allstate Ins. Co. — Cited for the proposition that, so long as there is a non-deductible guaranteed minimum, additional compensation that fluctuates with hours does not destroy salary-basis status.
• Higgins v. Bayada Home Health Care, Inc. — Cited for a textual reading of § 541.602(a): salary basis is satisfied if the employee receives a predetermined amount each pay period that is “part of” compensation and is not docked.

5. Managing opt-in collectives after the named plaintiff falls out

• Boudreaux v. Schlumberger Tech. Corp. — Provided a pragmatic template: where named plaintiffs are lost on summary judgment and remaining opt-ins show factual disparities, collective treatment may become unmanageable and decertification may follow. The Fifth Circuit did not order decertification, but relied on Boudreaux to justify remand: the record did not establish other opt-ins’ duties, compensation thresholds, or exemption applicability.

B. Legal Reasoning

1. The court’s regulatory selection rule: identify the “basis” of the guaranteed component

The panel framed the dispute as a gateway question: which regulation applies?

• If compensation is “computed on an hourly, a daily or a shift basis,” § 541.604(b) applies and requires (i) a weekly guarantee and (ii) a “reasonable relationship” between guaranteed pay and actual pay (with Helix/Gentry discussing a 1.5-to-1 benchmark).
• If the employee “regularly receives” a predetermined amount “by the week (or longer)” that is not reduced for quality/quantity variations, § 541.602(a) applies. Under § 541.604(a), additional compensation—including day-rate payments—may be added “without losing the exemption.”

The court’s decisive move was to treat Schlumberger’s plan as falling within § 541.602(a) because Guilbeau’s fixed biweekly payment was itself a qualifying predetermined amount that constituted “part” of his compensation. Once that is true, the fluctuating day-rate component is analyzed as permissible “additional compensation” under § 541.604(a), rather than as evidence that the plan is “computed” on a daily basis under § 541.604(b).

2. Textual emphasis: “all or part” of compensation

The opinion stresses that § 541.602(a) does not require the predetermined salary to be the whole paycheck; it must be “all or part” of compensation and must be non-deductible based on work variations. Guilbeau’s $1,826 biweekly guarantee satisfied those criteria, making the day-rate portion legally “immaterial” to salary-basis classification under the chosen pathway.

3. Why § 541.604(b)’s “reasonable relationship” test did not apply

The parties agreed that if § 541.604(b) applied, the plan would likely fail because Guilbeau’s total-to-guarantee ratio (5.9-to-1) vastly exceeded the “reasonable relationship” benchmark. The court nonetheless declined to apply § 541.604(b) because that section addresses workers whose compensation is computed on hourly/daily/shift units, whereas Guilbeau had a weekly-or-longer predetermined sum that independently satisfied § 541.602(a).

Put differently, the panel treated § 541.604(b) as a specific carve-in for pay systems that lack a true weekly (or longer) predetermined salary and instead calculate pay principally by time units worked—even if they include some guarantee. Guilbeau’s guarantee was not time-unit-derived; it was a fixed lump sum.

4. Scope discipline on remand

Although Schlumberger sought judgment as to the entire DD collective, the panel refused because exemption determinations also require proof of duties, thresholds, and other individualized facts. The court remanded for the district court to address whether the collective remains viable and whether other opt-ins meet the remaining exemption criteria.

C. Impact

• Clarifies the Fifth Circuit’s post-Helix roadmap for hybrid pay: A genuine predetermined weekly-or-longer guarantee (not derived from hourly/daily multiplication) can anchor § 541.602(a) salary-basis status, with day-rate pay treated as permissible add-ons under § 541.604(a). This narrows the circumstances in which plaintiffs can force § 541.604(b) and its reasonable-relationship test merely by pointing to large variable day-rate components.
• Strengthens employer defenses for oilfield hybrid plans: Employers can structure compensation with a fixed salary floor plus significant variable rig-day compensation while preserving exempt status—so long as the guaranteed component meets the regulatory minimum and is not subject to reductions based on work quantity/quality.
• Raises the stakes of how a guarantee is defined and documented: The contrast with Gentry v. Hamilton-Ryker IT Sols., L.L.C. signals that “guarantees” calculated as “hourly rate × minimal hours” may be treated as hourly-basis pay, triggering § 541.604(b) or failing § 541.602(a).
• Collective action management consequence: The court’s reliance on Boudreaux v. Schlumberger Tech. Corp. suggests that when a named plaintiff’s claim is resolved early, district courts should scrutinize whether remaining opt-ins are sufficiently similarly situated—especially where exemptions can “change over time” with duties and compensation.

IV. Complex Concepts Simplified

• FLSA overtime rule: Covered non-exempt employees generally receive overtime pay for hours over 40 in a workweek.
• Exemptions (HCE, executive, administrative, professional): Categories of employees Congress authorized the Department of Labor to exempt from overtime. This case focused on the “highly compensated employee” exemption and, within it, the “salary basis” requirement.
• “Salary basis” (§ 541.602(a)): The employee receives a predetermined, non-deductible amount each pay period on a weekly (or less frequent) basis, constituting all or part of compensation—i.e., a stable floor not reduced because less work was available or performed.
• “Additional compensation” (§ 541.604(a)): An employer may pay extra amounts (commissions, bonuses, or hour-based extras) on top of a guaranteed salary without destroying salary-basis status.
• Hourly/daily/shift computation and “reasonable relationship” (§ 541.604(b)): When pay is calculated by the hour/day/shift, it can still be treated like salary if there is (i) a weekly guarantee and (ii) the guarantee is reasonably related to what the employee typically earns; Helix and Fifth Circuit authority discuss a rough 1.5-to-1 ceiling as consistent with that concept.
• Interlocutory appeal (28 U.S.C. § 1292(b)): A discretionary appeal of a non-final order (here, denial of summary judgment) when a controlling legal question warrants immediate review.
• Collective action vs. class action: An FLSA collective is “opt-in” (workers join affirmatively), unlike Rule 23 classes that generally bind absent members unless they opt out.

V. Conclusion

Guilbeau v. Schlumberger Technology cements a practical and textual rule in the Fifth Circuit: where an employer pays a bona fide predetermined weekly-or-longer guarantee that is not reduced for work variations, the salary-basis test is satisfied under 29 C.F.R. § 541.602(a), and substantial day-rate/bonus compensation is treated as permissible additional pay under § 541.604(a)—without importing § 541.604(b)’s reasonable-relationship constraint. The decision reverses the denial of summary judgment as to the named plaintiff, while cautioning that collective-wide outcomes depend on individualized proof of duties and compensation thresholds, to be developed on remand.
