A judge has ruled that the National Labor Relations Board can require most private businesses to put up posters telling workers they have a legal right to form a union.
But U.S. District Judge Amy Berman Jackson limited how the board can enforce the requirement. She says simply failing to display the new NLRB poster isn't automatically a legal violation without other evidence of anti-union conduct.
The new posters are required effective April 30. They explain workers' rights to bargain collectively, distribute union literature and engage in other union activities without reprisal.
Berman's ruling Friday disappointed business groups that argued the poster is too one-sided and seems to encourage workers to join unions.
Labor unions call the poster a positive step in letting workers know their rights.
