LINDENHURST - Waldbaum's and Pathmark grocery stores are set to close across Long Island by the end the year, potentially leaving as many as 4,000 employees out of work.
The A&P Corporation, which owns the supermarkets, has filed for bankruptcy.
While many stores will close for good, some will be bought by companies like Stop and Shop. Other buildings will be put up for auction.
Union leaders say A&P is trying to cut employees' seniority benefits and 75 percent of their severance pay, even though both are guaranteed in their contract.
A court hearing will be held Monday on the company's request to cut benefits.
An A&P spokesperson refused to comment on this story.
A&P also filed for bankruptcy in 2010. Workers say they made a number of concessions at that time to keep the company afloat, including wage freezes, salary reductions and decreased vacation and sick time.
