Dec 19 (Reuters) - The workers' union representing more

than 10,000 Starbucks ( SBUX ) baristas said that union members

will go on strike in Los Angeles, Chicago, and Seattle on Friday

morning.

Workers United, which has a bargaining delegation that

represents workers at 525 Starbucks ( SBUX ) stores in the United States,

said walkouts are expected to spread each day and reach hundreds

of stores from coast to coast by Christmas Eve unless Starbucks ( SBUX )

and the union reach a collective bargaining agreement.
