Having come from another carrier that (we - the pilot group) used public shaming. I can say it works. At our current level, management is annoyed. But I'm sure they are wondering how much further this is going to go. Our campaign went on to use full page ads in the Wall Street Journal and mass picketing at the share holders meeting. In the end it worked. We avoided needless concessions and got a reasonable contract.
Every part of our operation has been run strictly through cost vs benefit analysis. Unfortunately, management hasn't been able to account for every cost. Hence, the lawsuit this week by investors and (what they feel) an unjust campaign against them by the union.
These are growing pains for a maturing company. Management can learn from these mistakes, or double down to the detriment of everyone.
