My 2 cents worth!
Most old farts have trouble remembering adjacent frequencies! They split sectors at various levels so we now need a laminated 'cheat sheet' for the first time ever. To do arrivals/en-route in various geographic areas is a guarantee for a mess up if ever i saw one. Where the flamin hell are the 'efficiencies' management continually talk about in the brave new world? All i see is more and more delays, traffic management etc. due no staff!
How will things be when we have no Ocean arrivals on a night shift into Sydney? Make sure you call in when you get out of bed youse early starters to tell `em your on your way!
