After voting down a potential agreement, the union that supports NJ Transit workers may go on strike Friday, impacting travel in and around New York City. But, NJ Transit services nearest Philly will remain operational.

NJ Transit is already preparing for the walkout by urging as many people as possible to start working from home.

Thousands of Shakira fans now have to find a new way to get to MetLife Stadium in New Jersey for her concerts, after NJ Transit announced it’s canceling train and bus service to the events on Thursday and Friday.

NJ Transit engineers are preparing to walk off the job on Friday, which could affect 350,000 commuters in New Jersey and New York City.

If the engineers do walk off the job, the agency plans to increase bus service, saying it would add “very limited” capacity to existing New York commuter bus routes in close proximity to rail stations and will contract with private carriers to operate bus service from key regional park-and-ride locations during weekday peak periods.

Shakira’s taking over MetLife for two nights next week — and tickets are vanishing fast. Especially for the Thursday night, May 15 show, the first of two nights for Shak's Las Mujeres Ya No Lloran World Tour in New Jersey.
