A group of Fargo, North Dakota, nurses were paid a subminimum wage for their “oncall” time. When on call, the nurses were required to be able to report to their hospital within 20 minutes, they were required to provide a phone number where they could be reached, and they were not to consume alcohol or drugs. After being called, nurses returned to regular pay. In three years, 36 of the 135 nurses who sued had been called in more than once. The nurses sued the hospital for violating the Fair Labor Standards Act’s minimum wage provision. Decide. Explain. See Reimer v. Champion Healthcare Corp., 258 F.3d 720 (8th Cir. 2001).
