ST. PAUL — About 4,000 janitors in the Minneapolis-St. Paul area are voting this week on a tentative contract agreement with about a dozen office cleaning companies.

The union representing the janitors said it reached an agreement with the employers on Saturday — averting a strike.

The Services Employees International Union Local 26 said the tentative contract includes raises of $1.20 an hour over three years and better health care coverage.

The janitors are employed by third-party contractors to clean corporate offices, including Target and Best Buy.

A phone listing for the Minneapolis St. Paul Contract Cleaners Association was not immediately available Sunday.
