"Are you talkin to me? Are YOU talkin to me?," asks George in his De Niro voice :)
A very interesting article Paul.
I've heard about LMX theory before, and I believe you have a superior understanding of its workings than I do mate.
That said, I do recall from past workshops that the bulk of the research on LMX focuses more on behavioral and job performance outcomes rather than on employee's job satisfaction.
If that is in fact the case, because employee job satisfaction can have many organizational benefits, this area may require a lot more research and investigation.
An A1 article from you Paul, our leadership maestro.
