The grievance has nothing to do with whether vacancies are offered. It has everything to do with how the contract spells out the procedure, which may not have been followed for LCO. This round of LUAL bids are a result of reallocation of ORD 747 flying to SFO, and follows the contractual procedure in the new and old UAL contract.
So, grievance would be doubtful for the reasons in the CO grievance. Maybe for other reasons, but not those. We really need the ISL done.
Enforce the contract, insist on it.
