Again, this seems to follow with 22.E.10 which states, "If no pilot bids on a First Officer category vacancy, the Company may assign an entry level pilot to fill the vacancy." No mention is made of a contingent vacancy. If that unfilled contingent.vacancy remains, the Company can (and likely will) post it on the next AE...unless they are trying to shrink a category and then it vaporizes.
