Industrial and Welfare Commission Order No. 5-2001 contains a special provision applicable to employees who are required to reside on the premises. These employees are required to be paid only for the time spent actually working, rather than their entire time on the premises, even if they are "on call." The Isners were resident managers of a non-profit home for the elderly. They were required to live on the premises. When they were "on call," they had to remain within earshot of call alarms and respond to "emergencies." They sought compensation for all on-call time. But the Court of Appeal decided that their employer, Falkenberg, compensated them properly for only the time they actually spent working.
The case is Isner v. Falkenberg. The opinion is here.
