New York officials urged commuters to work from home Monday after a strike by Long Island Rail Road workers shut down the nation’s busiest commuter rail system for the first time in about 30 years.

Governor Kathy Hochul said emergency transit options, including shuttle buses and extra subway service, were being deployed, but warned the system cannot fully replace LIRR service.

The strike followed the breakdown of contract negotiations between the MTA and a coalition of unions representing about 3,500 workers, with both sides blaming each other for the failure to reach an agreement.

Unions argued they are seeking fair wage increases amid rising living costs, while the MTA said the demands would lead to higher fares and taxes, NBC News has reported.

Talks resumed as officials and workers expressed hope for a resolution, but disruptions across the New York region are expected to continue.
