Sorry to hear that attitude still exists south of the border....when I started 30 years ago there was a definate them and us attitude, all the ATSA's young and just out of school, all the ATCO's mainly ex RAF and on their last legs,gradually as time has passed by things have changed....ATCO's now full of the flush of youth and ATSA's going grey and old!! Here north of the border I feel we all work together as a team....yes there will always be the exception, I guess on both sides but to be honest we all work in perfect harmony...I hope.
Mind you at time's I feel management, (at the very top that is) , also helps to keep that "them and us attitude".....for instance why as an ATCO should you benefit from free health care whilst the poor ATSA's have no such help...that to me is class distinction and I ask my management why??? If you want us to work as a team please treat us as equal team members!!
