A federal judge has ruled that the National Labor Relations Board cannot require private employers to post notices informing workers of their right to unionize. The court said that the posting of notices was not necessary to carry out the Board's mission, and that Congress did not delegate authority to the Board regarding such matters. Last month, another district court ruled that the Board did have the authority to require the posting of notices. The Board said that it is studying the ruling to determine its effects, as well as the response the Board will give. The ruling is expected to be appealed.
