They do; they can quit. I have to agree with "Eric Stratton", it is way past time for new legislation that would serve as arbiter for the myriad issues that surround the rights of labor as well as those who have a stake in the private ownership of the means of production. However, isn't that where the paradox lies because employees have a big stake in the profitability of the corporations for which they are employed? Maybe it is time for airline pilots represented by ALPA to reevaluate the merits and practicality of national representation and jettison the collectivism that is masquerading as some kind of sacrosanct brotherhood. ALPA "leadership" has been eating their young for generations.
