A couple things I want to correct on this post. Lots of great info, However MTA Bus is mostly represented by TWU Local 100, except for JFk/FR which is represented by ATU. The TWU Local 100 depots of MTA Bus are CP, BP, LGA, East Chester and Yonkers. There is a system pick each year where you can move around depots. OA oprators can work out of Manhattan, Bronx and Brooklyn and are represented by TWU Local 100 Also a system pick annually. TA Operators can work out of any borough and are represented by TWU Local 100 in manhattan, bronx and brooklyn. There is a system pick also. If they choose Staten Island they are stuck in that borough for the entirety of their career and are represented by ATU, They can move around Staten Island . If they pick Queens borough they are stuck at their depot for career without a system pick and is represented by ATU 1056.
