The Supreme Court has dealt a fresh blow to U.S. labor unions, delivering a ruling that makes it easier for employers to sue workers who go on strike. Thursday’s 8-1 opinion, authored by Justice Amy Coney Barrett, sided with a Washington state business that sued members of the Teamsters Union after their work stoppage left wet concrete in trucks, forcing the company to throw away the cement at a financial loss. Justice Ketanji Brown Jackson was the lone dissenter. The Working Families Party blasted the Supreme Court’s latest anti-union ruling, writing in a statement, “The institution that was at one point the last line of defense for working people against oppression and corporate greed is now a bludgeon wielded against those very people by the wealthy and well-connected.”
