Building Supervisor Confidence in Recognizing Impairment
It only takes a moment of inattention or poor judgment to put workplace safety at risk. For HR and Safety managers, training supervisors to identify signs of impairment is extremely important, because a small change in an employee’s speech, balance, or focus can be the first sign of a much bigger problem. When supervisors know what to look for and how to respond, they can stop small issues from turning into major incidents.
Physical Indicators to Watch For
Substance-related impairment can look different for each person, but there are common signs that may raise a red flag:
- Bloodshot or glassy eyes
- Slurred speech or difficulty forming words
- Unsteady movements or poor coordination
- Noticeable odor of alcohol or drugs
Physical symptoms don’t always mean drug or alcohol use. They can also be signs of illness, fatigue, or medical treatments, but in safety-sensitive jobs, they are too risky to ignore.
Behavioral Signs That Signal Concern
Changes in behavior can be some of the most telling indicators. Supervisors should be alert to:
- Sudden mood swings or irritability
- Confusion or difficulty following instructions
- Aggression or unusually confrontational behavior
These shifts can disrupt team dynamics and may indicate that an employee’s judgment is compromised.
Performance-Related Red Flags
Even before physical or behavioral changes are obvious, impairment can show up in job performance:
- Frequent mistakes or careless errors
- Missed deadlines or incomplete tasks
- A drop in attention to detail or focus
When these patterns appear, it’s important to have a private, documented conversation rather than letting the issue slide.
Distinguishing Impairment from Other Causes
Not all impairment is caused by drugs or alcohol. Fatigue, stress, family challenges, medical conditions, and even traumatic events can affect a worker’s ability to perform safely. A trained supervisor can:
- Look for multiple signs instead of relying on one clue
- Ask respectful, open-ended questions
- Follow company policy for reasonable suspicion procedures
- Involve a second supervisor or HR representative for witness and support
The goal is to respond with both consistency and fairness, keeping safety as the priority.
