The Supreme Court is set to hear Starbucks’s challenge on Tuesday to a federal judge’s order to reinstate workers who were attempting to unionize a store in Memphis.

Starbucks is asking the court to make it harder for the National Labor Relations Board to obtain intervention by judges in cases where a company is accused of violating labor law. The case stems from the February 2022 firing of seven workers who let local journalists into a closed store to conduct interviews about their unionization efforts.
