ATIS you’re facts are interesting, but the fact of really high percentuale of pilots and CC resign from SASI it’s not connected with the standards, but with other factors.
In Lufthansa, in BA or in EasyJet they have also high standards, but the % of people that resign is really low.
The environment of work like the quality of life are fondamental, if you don’t give that, yout must try to give something different, like Chinese companies, big salaries.
Is a fact that SASI doesn’t give any of those it is obvious that people join the company and after short time resign.
