Flight attendants for Continental Airlines rejected a proposed tentative agreement on Wednesday, saying it doesn't do enough to restore concessions they made previously.
The International Association of Machinists and Aerospace Workers said 55 percent of those voting rejected the deal. The union represents about 9,300 flight attendants at Continental.
The IAM said flight attendants want "full recovery of items sacrificed in the previous round of concessionary bargaining, such as sick leave, vacation," and a 401(k) match.
The union said it put the proposal out for a vote because it wanted them to see the 26-month agreement it had negotiated, including pay and a no-furlough clause.
Continental released a statement saying it "will continue to seek collective agreements with all of our unions that recognize the interests of our company and our co-workers."
Continental is owned by United Continental Holdings Inc., under a combination with United Airlines that closed on Oct. 1. Flight attendants from the two airlines are in different unions. The company has said it hopes to have the two airlines operating as one by the end of next year.
Shares of Chicago-based United Continental had risen $1.09, or 3.8 percent, to close at $29.53 in the regular session. They fell 3 cents in aftermarket trading.
