NEW YORK (WABC) -- Negotiations are once again underway between the Metropolitan Transportation Authority and a coalition of five striking Long Island Rail Road unions.
On Saturday, talks ground to a halt, shutting down North America's largest commuter rail system. By Sunday, the National Mediation Board stepped in, summoning management and workers to a meeting in Manhattan.
The federal labor agency governs labor relations for railroads and airlines.
CURRENT STATUS: Talks resume again Monday. LIRR unions remain on the picket lines.
Eyewitness News has team coverage of the LIRR strike.
The five unions represent about half its workforce, including engineers, signalmen and trainmen.
The unions and the MTA have been negotiating for months on a new contract, with talks stalled over workers' salaries and healthcare premiums.
