ShyGuy,

The answer is as simple as complicated. The fired pilots believed that they were following the rules the way ALPA interpreted and they thought they were ok. The company has decided that their interpretations of the rules(LOA) is different from ALPA's interpretation. The HGK pilots asked for a clarification of the rules from ALPA and the company and none has been given so far. The company decided to terminate the pilots because they have not followed their rules. The problem is.... no one knows what the rules are.

There you go....
