Stress in the workplace can be categorized as eitherfunctional (positive)ordysfunctional (negative). According toHuman Resource Management, 16th Editionby Gary Dessler,functional stress—also known as challenge stress—occurs when moderate levels of pressure motivate employees to perform at higher levels, learn new skills, and grow professionally.

In this question, Employee C is experiencing functional stress because being assigned a significant project for senior leadership presents a meaningful challenge. This type of stress can enhance focus, creativity, and job engagement, especially when employees perceive the challenge as an opportunity rather than a threat. Dessler explains that such stress can improve performance when it is manageable and supported by adequate resources.

The other options describe dysfunctional stressors. Fear of a harsh manager, confusion due to conflicting priorities, and routine tasks without challenge either create anxiety or fail to stimulate growth. Therefore, Employee C best represents functional stress.
