Thousands of Costco workers could go on strike starting Saturday

A large majority of 18,000 union members have voted to authorize a strike at 56 Costco locations if a new agreement is not reached. The union accuses Costco of not bargaining constructively or offering a fair contract despite the company's high profits. Practice pickets have already been held in California and Washington, and the strike could begin as early as tomorrow if negotiations fail.
