Long Island Rail Road workers were back on the picket lines at various spots in New York City and on Long Island on Sunday, voicing their concerns and demands as the strike continues for a second day. 

While the work stoppage has caused a mess for people heading to weekend events, the real concern is Monday morning's commute. The LIRR is the busiest commuter rail system in North America, with roughly 250,000 weekday riders. The strike is expected to force many to find alternative routes into New York City from from the Long Island suburbs.

The Metropolitan Transportation Authority says it has activated its contingency plan, which includes recommended subway stations as passenger drop-off points to get into the city. However, if you don't have a ride, there will be limited, free shuttle buses from several Long Island train stations to subway connections in Queens. Bay Shore, Hicksville, Mineola and Lakeview will go to Howard Beach-JFK Airport, while Ronkonkoma and Huntington will be bound for Jamaica-179th Street.

The MTA says it intends to issue pro-rated refunds to may monthly ticket holders.

Union, MTA exchange barbs

For months, the railroad's unions and the MTA have been negotiating a new contract, but talks have repeatedly stalled over workers' salaries and healthcare premiums.

With no deal, workers went on strike just after midnight Saturday and no new negotiations are currently scheduled.

"The MTA never really came to the table to negotiate until we had to call them out at their last board meeting," said Karl Bischoff, president of the Brotherhood of Locomotive Engineers and Trainmen. "There is no sense or urgency, as has been said before. It just seems like the MTA board is never held accountable. My members are always held accountable for their actions."

MTA President and CEO Janno Lieber issued a response on CBS News New York on Sunday morning.

"Just to be perfectly clear, we never broke off negotiations. The union elected to cut off negotiations and go on strike and inconvenience everybody. That was their choice," Lieber said. "We have been available every minute of every day, if they are serious about trying to bring this to a close. These are by far the best-paid workers in the entire national railroad system, and they want a better deal than every other MTA worker. That's not fair.

"These guys seem to think they are special, they are better than everybody else, and we're not going to blow the MTA's budget and put more burdens on taxpayers and riders because they think they are special," Lieber added.

Asked how long the MTA can sustain such a standoff financially, Lieber said, "Listen, the MTA is a big organization and if we don't have ridership, obviously, that hits the bottom line. It's not a secret that fares don't cover the entire amounts, so this is not a financial crisis right now for the MTA. It would be a financial crisis if we gave in and gave them, and then everybody else, a ton more money."

"I hope they could figure this out"

Though Monday's expected chaos looms, many weekend travelers have been left feeling confused and frustrated.

At the Jamaica station, normally a main transit hub in the city for LIRR riders and expected to be a main picketing location for workers, many commuters arrived unaware that trains are not running.

While the MTA has those contingency plans, the shuttle bus service doesn't start until Monday.

So weekend events like the Subway Series between the Yankees and Mets at Citi Field, the Bruce Springsteen concert on Saturday night at Madison Square Garden, and the Brooklyn Half Marathon, not to mention graduations and other events across the city, have been a real struggle to get to for Long Islanders who normally would get around on the LIRR without an issue.

"It would've been a 15-minute train ride. Instead, it was like an hour and a half to get here," Alex Lupo said at Citi Field on Saturday night.

"It's pretty annoying. I hope they could figure this out. It's really poor timing for this to happen during the Subway Series," Ryan Mattel added.

And with another Yankees-Mets game set to start at 1:40 p.m., the same travel scenario is likely to unfold. In other instances, some ticketholders for other concerts and Broadway shows had no choice but to give up their tickets because of the strike.
