At Will Employment San Antonio: The Rule Texas Wrote in 1888

Texas never passed a statute creating at-will employment. The rule behind at will employment San Antonio workers live under is instead judge-made. It dates to an 1888 railroad case.

In East Line & Red River Railroad Co. v. Scott, 72 Tex. 70, 10 S.W. 99 (1888), the Texas Supreme Court faced a service term left indefinite. Either party, the court held, “may put an end to it at will and so without cause.” Refusing further services is “no breach of contract.”

That holding still does most of the work in Texas employment cases. The exceptions came later, and they run narrower than most people expect. This article ranks them narrowest first.

At will employment San Antonio: what the rule actually says

The court restated the doctrine in Montgomery County Hospital District v. Brown, 965 S.W.2d 501 (Tex. 1998). Either side may end the employment “for good cause, bad cause, or no cause at all.”

A handbook rarely changes that. To limit the right to fire, an employer must “unequivocally indicate a definite intent to be bound.” But general assurances of job security do not qualify.

So the Texas at-will doctrine does not license every firing. It makes the reason legally irrelevant unless a carve-out applies. Each rule below therefore carves into the at will employment San Antonio default.

At will employment San Antonio and the Sabine Pilot exception

Texas courts have created exactly one public-policy exception, and it is tiny. Sabine Pilot Service, Inc. v. Hauck, 687 S.W.2d 733 (Tex. 1985), decided April 3, 1985, called it “a very narrow exception.” Three limits define it:

• The policy must come from laws “which carry criminal penalties.” So a civil statute or a company rule does not count.
• The exception covers “only the discharge of an employee for the sole reason” that the employee refused an illegal act.
• The employee carries the burden, and must prove “by a preponderance of the evidence” that the discharge had no other cause.

Picture two workers. One refuses an act a criminal statute punishes, and her employer fires her for that alone. She fits. The second refuses a task that breaks only an internal policy. He does not, since no criminal penalty attaches. Nor does a refusal plus a bad quarter, since a second reason defeats the sole-reason element.

At will employment San Antonio and workers’ compensation retaliation

Of the statutory limits on at will employment San Antonio recognizes, this one is cleanest. Tex. Lab. Code § 451.001 bars an employer from firing an employee for four things. Filing a workers’ compensation claim in good faith. Hiring a lawyer for it. Instituting a proceeding in good faith. Testifying in one.

Section 451.002 then supplies the remedy: reasonable damages, plus reinstatement for a discharged employee. But § 451.002(c) puts the burden of proof on the employee, not the employer.

At will employment San Antonio and the discrimination statutes

The Texas Commission on Human Rights Act supplies the broadest exceptions. Section 21.051 bars discrimination “because of race, color, disability, religion, sex, national origin, or age.” That list is the entire list. Section 21.055 then adds retaliation against anyone who opposes a discriminatory practice, files a charge, or assists an investigation. See the chapter’s text on the Texas statutes site.

Headcount then decides coverage. Section 21.002(8) requires “15 or more employees for each working day in each of 20 or more calendar weeks.” Counties, municipalities and state agencies count regardless of size. So a nine-person private shop usually falls outside chapter 21.

Sexual harassment: one employee, and 300 days

That 15-employee floor has a carve-out most San Antonio employment rights summaries miss. Subchapter C-1, effective September 1, 2021, defines “employer” for sexual-harassment claims as anyone who “employs one or more employees.”

So the three-person shop too small for a race claim is large enough for a harassment claim. Section 21.142 sets the standard. Liability attaches when the employer or its supervisors knew or should have known, then failed to take “immediate and appropriate corrective action.”

The clock differs too. Section 21.202(a) generally allows 180 days. Section 21.202(a-1) instead gives sexual-harassment complaints 300. Under § 21.202(b), the commission “shall dismiss” an untimely complaint.

Jury service and military service

Chapter 122 of the Texas Civil Practice and Remedies Code protects jurors; its title reads “Juror’s Right to Reemployment.” Read § 122.001 carefully, though: two 2019 amendments sit side by side in the codification, with different wording.

The remedies are unusually strong. Section 122.002(a) entitles an injured person to reinstatement plus damages of one to five years’ compensation. Section 122.0021 also makes a violation a Class B misdemeanor. Suit must still follow within two years of the service.

Military service runs through Tex. Gov’t Code § 437.204. An employer may not fire a member of the state military forces ordered to authorized training or duty. Section 437.204(b) calls that “an unlawful employment practice” and sends the complaint to the Texas Workforce Commission civil rights division.

The Texas Whistleblower Act covers public employees only

This is the most misunderstood rule in Texas employment law. The Texas Whistleblower Act, Tex. Gov’t Code ch. 554, does not protect private-sector employees. It protects public ones instead.

Section 554.002(a) bars a “state or local governmental entity” from retaliating against “a public employee” who in good faith reports a legal violation to law enforcement. Section 554.001(4) then defines that employee as someone paid to perform services for such an entity, excluding independent contractors. So a worker at a private company sits outside the statute.

The Texas Supreme Court twice refused to fill the gap. Winters v. Houston Chronicle Publishing Co., 795 S.W.2d 723 (Tex. 1990), declined to protect a private employee who reported illegal activity internally. Austin v. HealthTrust, Inc., 967 S.W.2d 400 (Tex. 1998), declined again, citing how “proactive” the Legislature had been in passing private-sector retaliation statutes.

Public employees face a short clock. Section 554.005 requires suit within 90 days. Section 554.006 also requires the employee to invoke the employer’s grievance procedure first, within that same 90 days.

Texas recognizes no implied covenant of good faith

Some states read a duty of good faith and fair dealing into employment. Texas does not. City of Midland v. O’Bryant, 18 S.W.3d 209 (Tex. 2000), held that “there is no cause of action in Texas” for that duty in an employer-employee relationship.

Non-competes after Senate Bill 1318

Tex. Bus. & Com. Code § 15.50 governs. A covenant is enforceable if it is ancillary to an otherwise enforceable agreement when the parties make it. Its limits on time, area and scope must be reasonable and no broader than necessary.

Two procedural rules favor employees. Under § 15.51(b), the employer must prove a personal-services covenant meets the § 15.50 criteria. Under § 15.51(c), a court finding the limits unreasonable must reform rather than strike them, and the employer then gets injunctive relief only.

Senate Bill 1318 reshaped the health care rules. A physician covenant under § 15.50(b) must now expire within one year of termination. It must also cap the area at five miles from the physician’s primary practice location. It must state its terms clearly and conspicuously in writing. And it must offer a buyout no greater than the physician’s total annual salary and wages at termination. New § 15.501 likewise imposes those same four requirements for dentists, nurses, and physician assistants. Both changes reach only covenants entered into or renewed on or after September 1, 2025. The codified non-compete sections carry the 2025 amendment lines.

The federal rule that would have swept this aside never took effect. A Texas federal court set it aside on August 20, 2024. The FTC then moved to dismiss its appeals on September 5, 2025.

What San Antonio cannot regulate

Since September 1, 2023, Tex. Lab. Code § 1.005 has preempted local employment rules. It names the occupied fields outright: “employment leave, hiring practices, breaks, employment benefits, scheduling practices,” and other terms exceeding state or federal law.

The House Bill 2127 litigation ended without a merits ruling. On July 18, 2025, the Third Court of Appeals reversed the judgment below on standing and dismissed the cities’ claims without prejudice. So the court never reached the merits.

San Antonio’s Sick and Safe Leave Ordinance never took effect. A court enjoined it, and the Fourth Court of Appeals affirmed that injunction on March 10, 2021.

The bottom line

“Wrongful termination” is not a category in Texas law. It is instead a short list of separate claims, each with its own statute, its own deadline, and its own burden of proof.

So the honest summary of at will employment San Antonio is a calendar problem, not a fairness problem. A chapter 21 complaint expires in 180 days, or 300 for sexual harassment. A public employee’s whistleblower suit expires in 90. A Sabine Pilot claim survives only when the refused act carried criminal penalties and was the sole reason. Outside those lines, the 1888 rule still answers the question.
