Good post Mr Chips

ATSA's do generally care about PPP, but after so many years (decades) of ATCO's walking all over them, they find it hard to speak out about anything! This is (of course) a generalisation (there are caring ATCO's out there

).
To add to our list of woes (and as an another example), why do non-op ATCO's get NOS, but ATSA's don't?
