Denver (AP) - Union workers at Safeway voted to authorize a strike, with workers possibly walking off the job as early as Monday, which could affect two of Colorado's largest grocery chains.
King Soopers and Safeway have agreed that one chain can lock out its employees if workers at the other chain go on strike.
Safeway says it's ready to renew bargaining, while King Soopers and the union last night agreed to extend its contract to May 30 while talks continue.
