"This is about fairness and respect for hard-working, frontline members who keep our communities fed and our stores running," said Jacques Loveall, president of UFCW 8-Golden State in a statement. "We’re calling on Safeway-Albertsons to do right by union members and agree to a contract that reflects their value and dedication."

The union said it is pushing for higher wages, funding for health care and pension benefits and scheduling provisions.
