That being said, while there is an interesting and at least plausible reason to believe there is some connection between such phenomenon and technology, i think the article is a bit too quick to proclaim that its things like "technology", "emailing" and things that have lead to a lack of empathy in the modern workplace.
On the contrary, i think organisational size and governance lines (which is in some ways connected to technology, admittedly), globalisation, outsourcing, and just the general economic and social realities of the modern workforce lead to a necessary degeneration of trust and respect between workmates and the organisation.
My company, for all its "values", will throw me under the bus to save itself, or for a quick buck. I cannot rely on it to support me into the future: even if it wanted to put money into a pension, i can't rely on that actually remaining solvent. I don't even know if my field/expertise is going to be around for the next 5 years. It is always looking to screw me over, outsource my labour, etc, etc. Its not "too much emails" that does it: its that I know I'm essentially working for a short-term psychopath that couldn't keep its promises to me even if it wanted to (and it doesn't want to).
If you raise people in harsh cutthroat conditions, don't be surprised if empathy falls by the wayside, or expect the lamb to lie down with the lion.
