Air Canada flight attendants have expressed a firm militancy tonight as they voted to reject a tentative deal for the second time in three months. This could place them on strike this Thursday. More than 65 per cent of members of the Canadian Union of Public Employees who voted opted to reject a proposed contract that was signed on Sept. 20 between union negotiators and management. In August, 88 per cent of Air Canada CUPE members who cast ballots rejected the earlier tentative pact. Globe and Mail
