The American Postal Workers Union is continuing to protest Staples stores and those protests are growing in size and frequency. The newest planned protests encompass 50 Staples stores in 27 states. The labor action comes after the USPS move to pilot selling some mail services at the office supply stores last November. The postal union, which represents about 220,000 active and retired USPS employees, has expanded its opposition by asking the California Federation of Teacher, which has about 120,000 members, to rally behind the union cause and boycott Staples until the risk to union jobs has been withdrawn.
