Most people has seen the data that using our smart phones (or other devices such as laptops, television, etc.) make it harder to fall asleep and get the rest we need each night. Base a leader, have you thought about how your own device usage may be a leading contributor to the ever rising employee disengagement statistics?  Research indicates the “blue light” of these devices is the culprit disrupting sleep patterns both in the short and long term. Many organizations applaud the mid-level and higher employees that are literally sleeping with their phones.  Do leaders really believe that the benefit of having ever-ready responsiveness outweighs the detriment of having employees who may not be getting the healthy rest and dis-connect from work that all the work-life balance and health gurus say we need? Leaders need to carefully consider the culture they are creating around this topic. Is the leader sending emails to his or her people at 11:00, midnight or later? Is the leader emailing on the weekends? And, is there an expectation of a response at these times or is this simply when the leader can catch his or her breath and get these emails/messages out? The following article offers some perspective on these issues and maybe a tip or two how you as a leader can be more smarter when it comes to the smart phone culture in their organization.
