While the time off had been in the works for the First Family of New York City, it was not clear until Monday that the LIRR would essentially be shut down due to striking workers.
Contract negotiations with the Metropolitan Transportation Authority fell apart on Monday and union reps for the workers say there will likely be a strike.
Despite the possibility of a strike that could affect 300,000 daily riders, many whom take the LIRR into New York City, Mayor De Blasio says he's taking his family overseas anyway.
"The city will be very well served. I will be in constant contact. When you have a family- one kid still in high school, one kid in college- it's very important to spend your time together," said De Blasio.
The Metropolitan Transportation Authority has a strike contingency plan that includes busing LIRR commuters. It is also encouraging riders to plan a vacation during the potential strike or make arrangements to stay with friends in New York City.
