Comprehensive and Detailed in Depth Explanation:
Surveys are the most efficient method to measure employee satisfaction because they can quickly collect data from a large number of employees in a standardized, anonymous, and scalable way. They allow for quantitative analysis (e.g., through Likert scales) and can cover a broad range of topics like job satisfaction, engagement, and workplace culture.
* Option A (Observation):Observation is subjective, time-consuming, and impractical for large groups, making it inefficient.
* Option B (Interviews):Interviews provide in-depth insights but are time-intensive and not scalable for large organizations.
* Option C (Surveys):Correct, as surveys are efficient, cost-effective, and can reach all employees while maintaining anonymity to encourage honest feedback.
