Which of the following is a signal that stress is affecting job performance?

• A. Increased motivation
• B. Improved attention to detail
• C. Consistent high energy
• D. Decreased job performance

Answer: (D)

When stress affects job performance, it tends to show up as a decline in how well tasks are completed. Stress uses up mental energy, narrows attention, and can slow thinking, which often leads to more errors, slower work, and lower quality. The option describing decreased job performance directly captures this negative impact and is the clearest signal that stress is harming how you perform on the job.

The other possibilities describe features that don’t reliably indicate stress reducing performance—someone might feel more motivated, stay energized, or appear unusually focused in the short term. Those don’t reliably reflect stress eroding work quality, even though stress can sometimes cause a temporary uptick in alertness. The key signal to look for is a consistent drop in performance over time.
