Not necessarily tru, Notso Fantastic - anyone that joins Southwest, for example, will have to have an (often self financed) B737 type rating and will initially be earning some 30% less than with other major airlines; and will work considerably harder. Equity and profit share schemes increase the take-home pay.
Southwest say they have something like 200 applicants for every position that opens - and most importantly of all, their staff turnover is one of the lowest in the industry.
The lesson therefore is that people who feel valued and part of a team will quite happily accept lower pay and poorer working conditions - so yes, fireflybob is quite correct.
