What should managers document when they suspect workplace impairment?
Objective observations, contemporaneously, by two trained people. A form completed after the result is worth nothing.

Direct Answer
Managers should document specific observable behaviors, dates, times, and work impact when they suspect impairment. It’s critical to focus on facts—not assumptions—to maintain fairness and protect your organization from liability. Practical, clear records help managers act confidently without overstepping or relying on memory alone.
Controlling authority: OSHA clarification of 11 October 2018 on 29 CFR 1904.35(b)(1)(iv). Texas has no general statute restricting private-employer drug testing.
Objective observation, recorded before the test
Documenting suspected impairment means recording objective details such as unusual behavior, speech patterns, odors, or physical coordination that impact job performance. This documentation should be factual and timely, avoiding personal opinions or diagnoses. By capturing what actually happened and when, managers create a reliable account that supports consistent follow-up actions and preserves institutional knowledge.
In real workplaces, managers juggle many demands and may hesitate to document for fear of legal exposure or employee backlash. However, documentation is not about accusing but about creating a clear, operationally useful record. It safeguards your organization, helps clarify expectations for all parties, and provides a defensible foundation if disciplinary or accommodation steps become necessary.
| Field | What to record | Why |
|---|---|---|
| Who observed it | Named observers, ideally two, both trained | A single untrained observer is the weakest possible position. |
| What was observed | Specific, objective, sensory observations — speech, gait, eyes, odour, coordination | “Seemed off” is not reasonable suspicion. |
| When and where | Date, time and location, recorded contemporaneously | A form completed after the result arrives is worthless. |
| Job impact | What the employee was doing, and what could have gone wrong | Connects the suspicion to a legitimate business need. |
| What was said | The employee’s own explanation, in their words | Frequently discloses a medication or medical issue that changes the analysis. |
| The decision and who made it | Named decision-maker and the time of the decision | Establishes that suspicion preceded the test, not the reverse. |
| Transport and safety | How the employee got home | Sending a suspected-impaired employee to drive is its own liability. |
A form completed after the result carries no weight
What I see employers miss is that documentation often gets too vague or emotional, which weakens its value. Saying an employee ‘looked off’ or ‘seemed strange’ isn’t enough. Instead, note specific behaviors like ‘slurred speech during morning briefing’ or ‘unsteady walking near workstation at 10 a.m.’ Concrete details matter more than impressions.
Another common gap is failing to document how the suspected impairment affects work duties or safety. Without linking observations to job impact, documentation feels incomplete. This omission can expose employers to challenges around fairness or reasonable suspicion. The operational risk arises when managers rely solely on memory or hearsay instead of a structured record.
Where impairment records fail
Incomplete or inconsistent impairment documentation creates multiple risks that can escalate quickly in real-world settings. Understanding these triggers helps managers prioritize accurate recordkeeping.
- Inability to justify disciplinary actions with clear evidence
- Employee disputes leading to grievances or claims
- Liability exposure from workplace accidents or injuries
- Loss of leadership credibility and morale issues
- Inconsistent enforcement undermining policy effectiveness
Train two observers before you need them
Before acting on suspected impairment, review your documentation for clarity, objectivity, and completeness. Check that notes include date, time, observed behaviors, and work impact without assumptions or medical conclusions. Confirm that observations align with your organization’s impairment policies and safety protocols.
It also pays to consider the context—such as prior performance or any accommodations—and whether the documentation supports a consistent approach across employees. This review helps ensure decisions are defensible and fair, reducing the risk of disputes or operational disruption.

When the observation is disputed
Consult HR promptly if documentation is unclear, if you’re unsure how to proceed, or if the situation involves potential disability or legal complexities. HR can help interpret policies, guide appropriate next steps, and ensure compliance with Texas employment laws.
Getting HR involved early also protects managers from acting on incomplete information and supports consistent leadership accountability. When managers feel supported, they can better navigate these sensitive situations without overstepping or delaying necessary actions.
