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.
