why would workers sabotage their own good thing?...
I don't know about everyone who works for Southwest, but my brother has been a Captain for them for many years. He has been making around a quarter of a million dollars a year for a long time.

“why would workers sabotage their own good thing?”
Greed and shortsightedness.
Unions have put companies out of business before. Rank and file union members usually dont have a good grasp of finance or economics. Union bosses are corrupt and greedy. Theyll plunder one company after another.
