As we reported earlier, the UK’s managers now routinely put in up to between one and two extra days of work a week thanks to the technological presenteeism associated with BYOD and other practices. But of course the phenomenon is not restricted to these shores. A survey from US business software firm BMC found that the average employee applying BYOD practices now works an extra two hours each day, a third check their emails between 6 and 7 each morning, each person deals with an extra 20 emails daily, and obviously does so using his or her own devices. You can either see this as an increase in productivity, or you can see it as more evidence of our willingness to subject ourselves to the round the clock work and the unblinking eye of the smartphone. What is also apparent from the BMC report is that while companies are overwhelmingly keen on the BYOD idea – some 95 percent allow it in some form – 84 percent offer employees little or no support and 64 percent do not train staff in security issues.  Infographic below: More →
