Here is an interesting article from the New York Times claiming that some companies seek to wean employees from their smartphones.
The article quotes Atos, an international information technology company and Daimler, the German automaker. And is mainly dealing with the effect of email dependency on employees productivity. One idea being to stop all internal emails, another idea being to delete all out-of-hours emails. Both seem very extreme to me.
Atos ... plans to phase out all e-mails among employees by the end of 2013 and rely instead on other forms of communication
Daimler ... incoming e-mail automatically deleted during vacations so they do not return to a flooded in-box
I love challenging blogs and this is one of them. I feel the problem is more to do with quality of emails being sent within companies, rather than the smartphone per se.
Possibly this is more to do with the Harvard professor mentioned "Leslie A. Perlow" selling his new book Sleeping with your Smartphone, I do like the title.
