Union members took to the picket lines Thursday in a two-week strike against King Soopers stores across the Denver area and in Boulder and Louisville.

Employees with King Soopers were up early Thursday morning to get on the picket line and go on strike after a series of issues they said they want addressed by the large grocery chain.

After union members approved a strike, UFCW Local 7 said a two-week walkout will “allow everyone to understand our concerns.”
