So Spiggit,
if we follow your logic ATCOs should not fight for a better rise 'cause we'll all be out of a job anyway at some indeterminate date in the future?
and, therefore, we should all kowtow to whatever miserly offer management think they can get away with?
by the way, still a fair number of signalmen (women) in this country; they just don't all sit in cosy little signal boxes anymore.
and for what it's worth the average signalman earns about 90% of a train drivers salary - probably a greater percentage than the average ATCO compared to a pilots salary.
never mind I shouldn't worry that my salary is eroding in real terms, I should just be grateful I've got a job...
