"Midwest has about 1,000 Milwaukee-area positions but is laying off its union pilots and flight attendants while replacing their aircraft with Republic jets. Those Midwest flight crews could be rehired by Republic, but only after their unions and the unions representing Republic flight crews merge their job seniority lists."

So they have no guaranteed jobs but can get REHIRED at RAH? Last I checked being re-hired means you go to the bottom of a list and thus through a interview process..... But you are right, the writting of this paragraph is terrible because then it goes onto to say, "Flight crews merge their job seniority list." So are they all being cut before the list are merged? And thus you just staple them ALL to the bottom?
