If the low-timer (or pensioned military pilot) wants to take the high road, they should refuse to work until the wage offer is sufficient. However, all low timers must be in agreement about what the "sufficient" wage is so they don't accidently undercut each other.
Also they need a source of income to tide them over until the pilot shortage becomes real enough to force employers to offer these sufficient wages. This source of income comes from...
...perhaps a little contribution from the working pilots who are enjoying a higher wage due to the shortage and the increased available overtime?
Hmmm, collective bargaining, employee contributions to a support fund, striking for better wages, where have I seen that before?
