Workers who clean some of Long Island's best-known malls will soon have more money in their wallets.

The workers' union, Local 32BJ, and the company that employs them, Control Building Services, have agreed to a four-year contract that will boost some cleaners' pay by as much as $3 an hour the first year, the union announced Friday.

The 171 Long Island workers covered by the contract clean at the Roosevelt Field, Source, Walt Whitman and Smith Haven malls, all owned by Simon Property Group of Indianapolis. Some of those workers were nonunion employees who cleaned the malls' food courts. After a long organizing effort, they are now members of Local 32BJ.

The union, part of the Service Employees International Union, said the minimum hourly rate for the cleaners will rise to $10.15 on July 1.
