Texas Workplace Investigations
Can a Texas employer terminate an employee during a workplace investigation?
Because Texas is an at-will state, you usually have the right to end employment at any time — including mid-investigation. But "you can" and "you should" are different questions, and the timing of a termination is one of the first things a claim is built around.

Direct Answer
Yes. In at-will Texas, an employer can generally terminate an employee while an investigation is open, as long as the reason is lawful and not tied to protected activity. But terminating before the investigation is complete is legally riskier, because the timing suggests the outcome was decided before the facts were in. The defensible path is usually to finish the investigation, document a legitimate business reason that stands on its own, and confirm the decision is consistent with how you've handled similar situations.
Sequence is what makes a mid-investigation termination defensible
At-will employment gives you broad authority, and employers sometimes read that as a green light to move immediately. The problem is that the right to terminate and the ability to defend a termination are not the same thing. When you end someone's employment in the middle of an open investigation, you create a timing problem: on paper, it can look like you reached a conclusion before you gathered the evidence, or — if the person you're terminating is the one who raised a complaint — like you're punishing them for speaking up.
The situation you're in matters enormously, and employers blur three very different scenarios. Terminating the subject of an investigation before it's finished suggests pre-judgment. Terminating the person who reported the concern is the highest-risk move on the board, because it's the textbook shape of a retaliation claim. And terminating someone for a clearly unrelated reason that simply happened to surface during the same window is defensible — but only if your documentation makes that independence obvious. Most of the risk here comes from employers treating all three as the same decision.
The systems point is this: an investigation exists to separate fact-gathering from the disciplinary decision. Firing mid-stream collapses those two things back together, which is exactly what the process was designed to prevent. If you've built a fair investigation and then short-circuit it, you've spent the effort and kept the risk.
Interim measures exist precisely so you do not have to decide early
The most common miss is skipping the interim step. When someone needs to be out of the workplace immediately — a safety concern, a serious allegation, an employee who can't be around witnesses — the answer is usually paid administrative leave, not termination. Leave removes the person and the risk while the investigation finishes, without locking in a decision you can't yet support. Employers who jump straight to termination give up that flexibility and the defensibility that comes with a completed process.
The second miss is consistency. Defensibility in Texas rarely turns on whether you had the right to act; it turns on whether you treated this employee the way you've treated others in similar situations. If a comparable case last year got a full investigation before any decision and this one didn't, that difference becomes the argument against you. Timing that deviates from your own past practice is evidence.
The third miss is assuming a resignation ends the matter. If the employee quits during the investigation, your obligation to complete a reasonable inquiry — especially into a harassment or safety complaint — often continues. Closing the file because the person left is how employers lose the documentation that would have protected them.
| Did the employee recently… | Statute | Effect on the decision |
|---|---|---|
| Discuss pay, hours or conditions with coworkers, including online | NLRA section 7 | Protected even with no union present. Discipline here is the classic unforced error. |
| Report discrimination, harassment or safety concerns | Title VII, ch. 21, OSHA | Retaliation is an independent claim that can outlive the underlying complaint. |
| Request or use leave, or an accommodation | FMLA, ADA, PWFA | Use of leave cannot be a negative factor in any decision. |
| File a workers’ compensation claim | Tex. Labor Code ch. 451 | Statutory retaliation claim. |
| Refuse to do something criminal | Sabine Pilot | Narrow, but absolute where the refusal is the sole reason. |
| Participate in an investigation | Title VII, ch. 21 | Participation is protected independently of the outcome. |
| Threaten to sue or contact an agency | Various | The threat itself is often protected opposition. Reacting to it converts a defensible termination into a retaliation claim. |
Where mid-investigation decisions fail
These are the triggers that turn a lawful termination into a contested one:
- Terminating the complainant or a witness, creating a retaliation timeline
- Terminating the subject before the investigation is complete, suggesting a predetermined outcome
- Inconsistency with how similar prior situations were handled
- Thin or after-the-fact documentation that can't show the reason was independent of the investigation
- Overlap with recent protected activity — a complaint, an FMLA leave, an accommodation request, a threat to sue
- Using termination when paid administrative leave would have managed the immediate risk
Separate the interim decision from the final one
Before terminating during an open investigation, confirm three things. First, is there a legitimate, documented reason that stands entirely on its own — one you could explain without reference to the matter under investigation? Second, is the employee connected to any protected activity, recent complaint, leave, or accommodation that would make the timing look retaliatory? Third, is this consistent with how you've handled comparable situations?
If you can't answer all three cleanly, the better move is almost always to place the employee on paid administrative leave, finish the investigation, and make the decision on a complete record. Review your existing documentation the way an outside reader would: does the file show a fair process and an independent reason, or does it show a decision that arrived before the facts? That gap is what you're managing.

When the conduct cannot wait for the finding
Bring in support before you act whenever the employee is the person who raised the complaint, is on or returning from leave, recently requested an accommodation, or has threatened legal action. Those are the fact patterns where a defensible termination and a costly one look identical on day one and only diverge based on how carefully the timing and documentation are handled.
It's also worth a second set of eyes when the allegation is serious enough that you feel pressure to act immediately. That pressure is real, but it's usually best answered with administrative leave and a fast, thorough investigation — not a termination you'll have to reconstruct a justification for later.
