No we use to have all the backshops in CLT, some in PIT, and our landing gear and plating shop was in INT.
We lost 46% of out maintenance workforce including 900 Utility ( Aircraft cleaning line, heavy and shops) when our CBA was abrogated.
No one likes it but it is what it is.
We also have a protected headcount between CLT and PIT heavy. Also the work done in PHX hangars are protected.
Also certain line stations can’t be closed and we have a minimum number of how many line stations must be open.
