I would say the union acted ethically, reasonably and responsibly. The union gave choices to the pilots and those choices came at the behest of management. Management presented options, some of which likely didn't make it to the pilots. At the end of the day the pilot chooses to participate in these voluntary programs or doesn't. I am ok with that. I don't view it as a concession, i simply view it as a choice. Some pilots may take this down time to do the things they've wanted to do and couldn't get the time off. It's a choice. it's voluntary.
