Spirit management just file a lawsuit in Federal District Court alleging a Major Dispute. The whole point of the RLA's Dispute/Grievance process it to keep the courts from being bogged down by small contract Disputes (eg. they messed up your trip rig - Minor Disputes), and to keep commerce flowing by rail (now air).

This isn't a 2 year Grievance in front of a System Board. This is a Federal Judge deciding whether irreparable harm is being done to Spirit by the pilots, and, if so, whether an immediate injunction (Temporary Restraining Order - TRO) should be granted. If it's granted, and violated, more bad things happen. I'm not sure if/when a penalty phase occurs without violating a TRO, but I think fines can be a part of the initial ruling if the judge wishes.

Don't repeat historical mistakes (and don't post things online that you don't want brought into a lawsuit).

"On February 13, Judge Kendall issued a contempt of court citation against the union and two of its leaders. The judge assessed temporary fines—$10 million against the union; $10,000 against Richard LaVoy, the union’s president; and $5,000 against Brian Mayhew, the union’s vice-president—for violating the TRO issued 3 days earlier. The judge specifically cited a February 10 communication from the union leadership to its members, which, the judge said, '“...intentionally gave the impression and further conveyed to the union membership that individual Union members did not have to comply with the TRO.”',"...Two days later, Judge Kendall ruled that the APA and its top leadership must pay American Airlines $45.5 million in compensatory damages. One day later, he issued a permanent injunction prohibiting the union from conducting a job action until its current collective bargaining agreement expires and the mandatory procedures of the RLA have been exhausted."
