UNIVERSAL CITY Two trade groups representing large hotels in Los Angeles filed for a preliminary injunction to block the city from implementing its law raising hotel wages. The American Hotel & Lodging Association and the Asian American Hotel Owners Association asked the court to suspend implementation of the law set to take effect July 1 until a decision is reached on a prior lawsuit alleging that the wage hike improperly disrupts the relationship between labor and employers set forth in federal law. The city ordinance requires an estimated 80 hotels with more than 150 rooms to pay their workers at least $15.37 an hour. The measure would affect at least seven Valley hotels, such as the Hilton Los Angeles/Universal City with 489 rooms.
