1. GET /compensation
   Your primary source of truth for all things pay-related:

• Current pay rates (the foundation of band compliance)
• Pay frequencies (crucial for standardization)
• Pay currencies (essential for global operations)
• FLSA status (helps determine applicable rules)
• Start dates (for tracking changes)

b. GET /pay_group
This helps organize and structure your salary bands:

• Group names and descriptions
• Specific pay rules per group
• Band definitions and limits

c. GET /employment
Adds vital context to compensation data:

• Job titles (for band assignment)
• Employment types
• Department information
• Effective dates

First Layer - Band Definition:

• Map job titles to appropriate salary bands
• Set up minimum and maximum thresholds
• Define acceptable ranges for each level
• Account for different currencies and locations

Second Layer - Active Monitoring:

• Compare current compensation against defined bands
• Flag out-of-band salaries immediately
• Track upcoming band transitions
• Monitor promotion-related band changes

Third Layer - Exception Handling:

• Identify approved exceptions
• Document justification for out-of-band cases
• Track temporary allowances or special circumstances
• Monitor exception durations
