Understanding Salary Distortion
This situation, where the salary of a staff member is higher than that of their supervisor, is what we call "salary distortion" in compensation.
Salary distortion can occur when a company lacks a valid salary structure based on appropriate job grades and job classes. In some countries, like India, this issue is particularly problematic because there is confusion between the terms "salary component" and "salary structure."
Preventing Salary Distortion
To avoid salary distortion, companies must adopt a valid salary structure based on job classification and job grading. A well-defined salary structure with valid job classes and job grades will determine the rate range for each job grade and class. Consequently, supervisors will always have higher job grades and, therefore, higher salary rates. Non-supervisors will have their respective rate ranges, but these will always be lower than those of supervisors.
Please remember that your company must always have a salary structure compliant with the first compensation principle of internal equity—i.e., larger roles must be compensated more than smaller roles. Therefore, paying a staff member a higher salary than their supervisor violates this principle and should be corrected.
Best regards.
