"The analyst told TPG, Delta may be dealing with a so-called “Blue flu,” where some pilots called in sick or refused to volunteer for flights because of potential job cuts and/or reductions in pay. The analyst said there may have been issues of misalignment with crewing and scheduling, and some unrealistic expectations about how many flight attendants and pilots might volunteer to work additional days during the Thanksgiving week"

Blue flu? Is this some form of protest? Wild accusation against the character of the pilots. Is it crazy if this is true or is it just normal labor guerilla warfare.
