The International Association of Sheet Metal, Air, Rail and Transportation Workers-Transportation Division (SMART-TD) reached a tentative five-year agreement with Keolis Commuter Services, the contract operator of Massachusetts Bay Transportation Authority commuter rail services. The agreement is retroactive to July 1, 2023, and will include 5% raises each year, plus an additional $2 per hour in 2027, as well as three additional sick days per year, the addition of Martin Luther King Jr. Day as a paid holiday, and changes to vacation allotments and bereavement leave. SMART-TD represents 450 Keolis employees, who still need to vote to approve the agreement.
