Significant worker strikes this year in the U.S. involving dockworkers, Boeing machinists, and Starbucks employees were driven by disputes over wages and working conditions. The dockworkers' strike -- across 36 ports -- was temporarily resolved with a conditional wage increase, while Boeing machinists ended their strike with a new contract but faced subsequent layoffs. Starbucks employees continue to strike over unmet labor agreements, affecting operations across major cities.
