I am not an employee and don't know how the pay system works. So, I can't add any info.
I am curious how pay is determined in the ATSS ranks.
In my most current position (mechanic), the perspective employees' experience and training was evaluated (with firm guidelines). From there, raises were basically automatic (given no performance issues) until the mechanic was 'topped out'. This is assuming the employee remained in the mechanic ranks (not promoted or transferred to a 'merit' position).
Like I said, I am curious how the ATSS pay system works.
