NLRB: Workers must be told of union rightsThe National Labor Relations Board issued new regulations on Thursday that require companies to put posters on their bulletin boards that inform employees about their rights to unionize under federal law. Under the new regulations, businesses must display notices that explain the right to bargain collectively, to give out union literature and to work together to improve wages and conditions free of retaliation.

Noting that many workers are unaware of these rights, the board said the new regulations are aimed at making it easier for workers to exercise their rights under the National Labor Relations Act, which sets rules for unionization efforts. Agricultural, rail and airline employers are not covered by the new rule.

Business groups were quick to criticize the new regulations, which they said are part of the board's pro-union tilt under President Obama.

The board's chairwoman, Wilma Liebman, steps down on Saturday when her term expires. The new regulations are part of a last-minute push by the board's 3-to-1 Democratic majority to finish cases before she leaves.

Radio service Pandora's revenue jumps againIn its first quarterly earnings since going public, Pandora Media, the firm behind the Internet radio service Pandora, reported increased revenues, as well as continuing growth in subscriptions and mobile advertising. For the three months that ended July 31, Pandora reported $67 million in revenue, up 117 percent from the same period a year ago. Pandora posted a net loss of $1.8 million, or 4 cents per share.

Cakebread, the chief financial officer, said that 37 million users tune in at least once a month.
