Omaha Steve's Labor Group

At first glance, the Supreme Court did seem poised to issue a decision more damaging to unions. Thursday's ruling followed three earlier decisions against labor in the last five years, including one that reversed a 40-year-old precedent. And the truckers' case posed the possibility that the court would overturn another longstanding precedent dating back nearly 70 years. So labor feared the worst: a decision that would hollow out the right to strike. Thursday's decision, however, was a narrow ruling that generally left strike protections intact.

For nearly 70 years, the Supreme Court has said that federal law gives the Board the authority to decide labor disputes as long as the conduct is even arguably protected or prohibited under the federal labor law.

At the same time, the court's majority decided the case in favor of the company in a very fact specific way. The court ultimately said the union's conduct in this particular case posed a serious and foreseeable risk of harm to Glacier's trucks, and because of this intentional harm, the case should not have been dismissed by the state supreme court

There are 27 cases still to be decided by the court, as it enters what is usually the final month of the court term. And many of those cases will be highly controversial. In Thursday's case, though, the court, quite deliberately took a pass. If there is to be a major retreat on long-guaranteed labor rights, it will not be this term, and labor leaders were relieved.
