A psychological study to determine the harmful effects of sleep disruption asked a company to start an overnight shift without notice. Many of the employees began to have accidents while on the job.

The study is planned to last for two weeks. Why would an institutional review board be hesitant to approve this study? Responses
The researchers are disrupting sleep for an extended period, which may cause harm.
