Why would you want to unionize? Why be tied to the Railways Labor Act restrictions?
1. You can't strike (yes, technically you can but let's face it, it takes a miracle that happens 0.1% of the time)
2. In this day and age, I would think if the pilots want to send a message to management, can't everyone just set up a web site or twitter account or mass e-mail distribution and set up a day and call in sick? Wouldn't that have the same effect? Either way management is going to be ****ed (union or not). I would think you'd get a lot more immediate attention when planes are grounded until demands are met without having the drama of dragging out contract negotiations that could last for years with back and forth bickering.
