Isn't the money there??
DHL/DP put up the money, but left it to ABXA management as to how the money is to be distributed. Mgt wants the money to prop up the pension fund because they left it underfunded. The pilots want the money for severance. Both parties are embroiled in end game, across the board, concessionary contract talks.
So it looks like the culprit here is not DHL/DP, but ABXA management.
