There will be no need for strike action IMHO.
Airservices says we have 972 Operational Controllers and are 17 short.
We actually have around 750 'moving metal' controllers which makes us 220ish short.
Between now and christmas we will lose say at least another 12-15 to resignation/retirement/VR etc (we have lost about 4 the last few days). Hopefully we will pick up 12-15 new ratings in that period.
End result? 220 short. Its a house of cards built on a fold town tray table and the FO (Civilair) mentions to the Capt (Alan Woods Building) that he is reading a SIGMET outling forecast MOD CAT ahead. "Shall I make a PA announcement and tell the pax?", "No need the WX radar looks fine, tell them the weather ahead is beaut and we will be on time", "But Captain, its Clear Air Turbulence and the Sigmet says...".
The issue is have we passed the PNR (point of no return)?
We don't have to do anything. Go to work, be professional - Levels 1, 2 and 3 are punching the holes in the cheese slices.
