(Portland, OR) -- Union members who work at Kaiser Permanente in Oregon are ready to go on strike. The union says 96-percent of participating members voted to approve the strike with 90-percent of the members voting. If the strike is approved by union leaders, workers would have to give ten days of notice before the strike could begin. The union says the major issues are staffing and a two tiered pay system, where new workers make less than workers with more time on the job. Kaiser says it pays workers above market rate. The union disagrees.
