Yes, always read who is saying the message, CAE, they arent going to call it like it is.
BALPA said over 1,000 experienced pilots unemployed currently in the UK and around 15,000 in Europe now. That is enough for a several years recruitment even a heavy demand if it does springs back.
What people havent yet realised is that big companies are getting rid of floors of their offices and indeed their whole offices, one major bank closed down an office for 2,700 people and made them all homeworkers!! As people can be home based saving company time and money, big studies in IT showing that home workers are more productive as dont waste time travelling and for those a bit older with families etc, they prefer it. Alan Sugar was complaining that people were working from home too much, now that Zoom, MS Teams working is normal, business travel will never be the same again, it has decreased for ever! There is not a need for a large amount of people to travel regularly for work, some business travel will happen but also people realise that Zoom etc can also be used for social gatherings so that is likely to decrease some leisure travel.
Save your money and do something else with your time, only once has their been an actual pilot shortage, it was during WW2!
