If injuries reduce at a workplace but employee satisfaction does not increase which reason is possible?

Correct answer: The improvement increased safety but left comfort or workflow problems

Direct answer: Option A, because the improvement increased safety but left comfort or workflow problems. Ergonomics has more than one goal. A good workplace should reduce injury, support comfortable posture, make tools easy to use and allow work to flow efficiently. Follow the case: injuries decrease, so the safety part improved; however, employees may still face awkward layout, tiring movements, noise, poor temperature, slow procedures or uncomfortable equipment; these remaining problems can keep satisfaction unchanged. Option A explains both facts without contradiction. Option B is wrong because fewer injuries are a positive sign, not automatically a wrong sign. Option C is wrong because satisfaction can be affected by workload, comfort, control and work conditions. Option D is wrong because assessment is still needed to find unresolved problems and check whether the change works for workers. Option A is a useful reminder that one ergonomic measure should not be judged by one result alone. Exam cue: evaluate safety, comfort and workflow separately.
