Janitors Agree to Pact With 2 Aerospace Firms

Aramark Corp. janitors who clean industrial plants and local offices of aerospace companies Boeing Co. and Northrop Grumman Corp. returned to work after settling a three-week strike for higher wages.

The agreement negotiated with Local 1877 of the Service Employees International Union will increase the janitors’ base pay to $8.10 from $7.25 an hour over three years and provide healthcare insurance starting in the third year of the contract.

The settlement is part of the same contract ratified by union members Friday with cleaning companies Servicon Systems Inc. and Somers Building Maintenance Inc.
