Peace of mind
More than the salary its the "peace of mind" people are looking for, I think Indian pilots are getting fed up of a lot of things like -
The ****ty managers with absoultely little experience and no understanding of airline operations running them like a local mom-n-pop shop.
The so-called doctors who sit on the medical dept who probably cannot prescribe anything more than an aspirin, putting people down for the most absurd reasons.
The constant inefficiency of the whole aviation system in India, which just gets worse with every pasing day.
And much, much more....
In the end, people need a life not a struggle....
