Which metric focuses on analyzing the root cause of grievances?

Causal analysis is the metric that specifically aims to identify the underlying factors or reasons behind grievances within an organization. By focusing on causal analysis, HR professionals can delve into the "why" behind employee complaints or issues, which is critical for fully understanding the impact of these grievances on the workplace.

This method often involves collecting data, analyzing patterns, and examining various aspects of the work environment that may contribute to employee dissatisfaction. The insights gained from causal analysis can help organizations implement effective solutions to resolve issues, thereby improving employee satisfaction and reducing future grievances.

In contrast, the other options represent different approaches to handling grievances rather than focusing on their root causes. For example, evaluating the average close time may help in determining how quickly grievances are resolved but won't explain why they occurred in the first place. Similarly, identifying grievance sources may provide insight into where issues are arising, but it does not delve deeper into understanding why those issues exist. Lastly, assessing costs associated with grievances focuses on the financial impact rather than the underlying issues.
