Who started the War for Talent?

I’m not the first to decry the use of the phrase “War for Talent” (see for example this blog by Workable). While I’m sure nobody wishes to downplay the true horror and suffering that is war through the use of such a metaphor, it is rather an apt one for the current recruitment market. I’m referring not only to the blatant mistreatment of undervalued candidates, but the lengths that the “top” organisations will go to in meeting their objectives of hiring only the best talent.
