Los Angeles Airport Hilton

On some days, Christine Hsu scarcely sees the city whose political and labor leadership her family has up in arms. Instead, she stays inside the Hilton Los Angeles Airport, the hotel her father bought, the hotel his company still owns, the hotel where she and her brother live for weeks at a time, 15 floors above Century Boulevard. The Hilton, with more than 1,200 rooms, is the second-largest hotel in Los Angeles County.

In what may be the first action of its kind, California workplace safety regulators have charged that the duties performed by housekeepers at a hotel -- scrubbing, bed making, vacuuming -- violate the state's repetitive-motion rules. A citation issued late last month by the Division of Occupational Safety and Health identified eight infractions at the Hilton Los Angeles Airport hotel.
