This study by research group RAND Europe, published in November 2016, has confirmed what the science has already made clear: lack of sleep = lower productivity and performance. That costs money. Employers need to start taking a more active role in ensuring their employees are better rested. This may include reestablishing expectations for when employees must respond to calls and emails, ensuring employees leave the office by a certain time, and by promoting an open dialogue about healthy sleep habits. CTV News wrote a story on the study titled Lack of sleep costs Canada billions of dollars in productivity: report and does a great job at highlighting the details.
