“Demonstrations are planned at two Massachusetts Walmarts to protest alleged company retaliation against 80 workers who went on strike in June — including two Bay Staters — and the firings of 20 others.

The union-backed protests will be staged today in Chicopee and Saturday in Chelmsford. They follow similar events scheduled yesterday in 14 other cities.

David Coulumbe, a cart pusher at the Chelmsford Walmart, and Chicopee cashier Aubretia Edick received warnings for excessive absences after their strike participation, according to Russ Davis, executive director of Massachusetts Jobs With Justice.”
