> As put by a 2006 academic paper from Ian Towers, a researcher from SRH Hochschule in Berlin, mobile technology “increases expectations: managers and colleagues alike expect staff to be almost always available to do work”.

A little surprised to see this line. In Germany, there is a law (cannot recall the name), that effectively states that you cannot be fired if you don't reply to a work email or phone call between 6pm and 9am. If you want to, you can, but it cannot be held against you.
