After two years of working without a contract, a recent arbitration decision set the terms of employment for nearly two-thirds of all Metro employees through 2020. Union members get a small raise retroactive to 2017. In exchange, they will have to pay a higher percentage of their health care costs moving forward. On net, that means labor costs will go up over $60 million through 2020 and WMATA will look to Arlington, among other jurisdictions, to fill in that gap.
The issue that will have the biggest impact on the long term health of the transit agency is pensions. The second largest union has agreed to move to a defined contribution plan for new hires. The largest union refuses to do so.
