Comprehensive and Detailed in Depth

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.

Option D (Focus groups): Focus groups offer qualitative insights but are less efficient due to the need for small group facilitation and limited scalability.

The aPHRi curriculum emphasizes surveys as a key tool for collecting employee feedback under employee relations.
