The greatest disadvantage of a foreman/supervisor conducting his or her own incident investigation is that he or she ____

• A. May Find It Difficult To Remain Unbiased
• B. May Be Perceived To Favor Management
• C. Becomes Biased Due To Familiarity With The Work
• D. Does Not Have Time To Investigate

Answer: (C)

The main issue here is impartiality in investigations. When a foreman or supervisor conducts the investigation, they are deeply embedded in the work environment, know the processes, and are familiar with the people involved. This closeness can lead to bias—they may interpret evidence in a way that fits their experience, overlook certain findings, or subconsciously protect the team or themselves. That bias compromises the objectivity needed to accurately identify root causes and assign accountability, which is why independence in investigation is so important.

Other potential concerns, like being perceived as favoring management or simply running out of time, can occur but are secondary to the fundamental problem: familiarity with the work creates a biasing influence that undermines the integrity of the investigation.
