So a rogue Spirit pilot created a gravy choker website listing names and descriptions of pilots who are picking up open time and used deragotry terms.    That's got lawsuit written all over it.    The site was taken down.
What unity do you possibly hope to get with actions like this?
If your contract allows up to 5 JAs per year, and picking up open time, then you have no legal basis to get them to stop operating as your CBA already allows.
Also, the company can easily win a lawsuit over what pilots have been posting on forums and what is happening in real life.    They have historic data.   If Jan, Feb, March, April, and May historically has x amount of open time flying picked up, but this time, it's a number far below x, they will make a case for a work action, and based on what quite a few dummies on APC have posted, the company will probably win.      It's happened before, and pilots lost.
Contract now, sure.  But tread carefully.
