What is the difference between longevity pay of up to 20 years versus longevity pay of 20 to not more than 25 years if done through the meet and confer process?

Effective July 1, 2023, a unit providing for longevity increases for more than 20 years but not more than 25 years through the meet and confer process, then increased longevity pay is included in the new definition of salary of a first-class patrolman or firefighter. If a unit does not follow the meet and confer process, then the longevity pay of up to 20 years is included in the salary. See IC 36-8-1-11.
