What is one potential consequence of workplace stress in laboratory settings?

In laboratory settings, workplace stress can significantly impact performance and safety. Higher risk of errors arises when employees are stressed, as it can lead to decreased concentration and impaired judgment. Stress can contribute to burnout, fatigue, and a sense of overwhelm, all of which hinder a person's ability to perform tasks accurately. For instance, when workers are preoccupied or anxious, they might overlook critical details or skip important steps in procedures, which can have serious implications in a laboratory where precision is vital for accurate results.

The other options suggest positive outcomes that are typically not associated with high levels of stress. Improved work relationships, increased operational efficiency, and enhanced staff morale are generally seen in healthier, supportive work environments, not in situations where stress is prevalent. Therefore, the potential consequence of workplace stress in laboratory settings is most accurately represented by the increased risk of errors.
