The Service Employees International Union's bargaining committee says workers will receive an average cumulative pay increase of nearly 7 percent over the next four years and a $600 bonus the first year.
The agreement also maintains employer-paid health care and pensions. It is subject to ratification by union members.
The agreement was reached Tuesday between the service workers union and the Building Owners Labor Relations, Inc., an organization representing some of the city's major commercial office building owners, managers and cleaning companies. The workers clean and maintain corporate office buildings in Philadelphia.
