The Supreme Court struck down a ruling over what union members can reasonably do during a strike.
A local teamsters union in Washington walked off the job in 2017 with trucks full of wet concrete.
Justice Ketanji Brown Jackson was the only dissenter, saying the decision jeopardizes union rights.
The solo dissent was a first for the outspoken Biden-appointed justice, who wrote that the ruling would "erode the right to strike."
"Workers are not indentured servants, bound to continue laboring until any planned work stoppage would be as painless as possible for their master," Jackson wrote.
