(Associated Press) - About 20 janitors are staging a one-day strike at Park Meadows Mall in suburban Denver.
The Service EmployeesUnion went on strike Tuesday.
The union says the mall's cleaning contractor has been making it difficult for workers to organize. It says union supporters have been put under surveillance and workers have been told not to talk to union representatives.
A telephone message left for a company spokesman wasn't immediately returned.
SEIU says the strike is one of 20 demonstrations planned at malls nationwide owned by-based General Growth Properties. Top of page.
