The Massachusetts Bay Transportation Authority (MBTA) states that a recent arbitrator?s award to retroactively grant wage increases totaling up to $88 million could place the public transportation organization in ?financial jeopardy?. The union representing the workers due to receive the back pay claims that the MBTA?s claims stem from a dispute with no legitimate basis. Negotiations broke down in 2010 due to the MBTA?s effort to have the Carman?s Union take on more of their health insurance cost and defer wage increases. The union and the MBTA have filed dueling lawsuits over the arbitration award.
