Lyft Inc.'s workplace policies addressing intellectual property and confidentiality comply with federal labor law, according to a National Labor Relations Board memo released Friday.

The memo, prepared by the head of the NLRB's Advice Division in the general counsel's office, said the ride-hailing company's rules for confidentiality and intellectual property do not interfere with the power of employees to participate in union-related activity. The memo indicated that the allegations a union brought against Lyft should be dismissed.

The memo incorporated President Donald Trump-appointed general counsel Peter Robb's new guidance on workplace handbooks. That new guidance, issued in June, “increases confidence that many workplace policies previously ruled invalid will not be challenged under the board's new legal standard,” management-side firm Littler Mendelson said in a post last month.
