Pay scales for every job code and pay rates for every public employee should be public information. I’m not getting eight percent anywhere except inflation.
The federal pay scales are public

This is the federal pay scale for the Los Angeles Geographical area.
A typical federal employee would start out as a GS-7/GS-9 and get step increases for longevity and/or get promotions to reach journeyman level or supervisory positions typically GS-13 and higher.
Some positions are in a high grade and non-supervisory. For example, at LAX Tower, the journey grade for Air Traffic Controllers is a GS-14, so a non-supervisory controller who is at the mid-point in step increases is currently earning $145,326/yr.
