The union representing city bus and subway workers overwhelmingly ratified a contract it had rejected two months ago on Tuesday.Of 20,593 votes cast, the Transport Workers Union Local 100 cast 14,716 votes for the contract, union President Roger Toussaint announced. Toussaint led the union walkout after contract talks with the MTA broke down over issues including health care and pensions.By a seven-vote margin, the union rejected the same contract with the MTA in January. Union leaders had urged the rank and file to accept the deal that ended a three-day strike of the nation's largest transit system just before Christmas. Toussaint said the difference between the seven-vote defeat and Tuesday's vote is that members at that time were confused and deceived by how much health insurance they would have to pay. Tuesday's vote came a day after a judge fined the union $2.5 million for the strike - $1 million for each day of the walkout. The strike violated the state's Taylor Law, which bars public employees from striking. Related Story
