yinless yang or yangless yin?

Employees of the corporate world are no doubt familiar with crapspeak and its unfortunate and inevitably growing influence on the English language. One of its many contributions is the innocuous (and banal) phrase senior management. I am sure those that drop it in all their correspondence (usually to their underlings far removed) nurse thematically rich notions of meaning and semantics for this phrase, but those of us at the receiving end fail to see the difference between this phrase and phrases like program management and senior leadership.

And suddenly today, I wondered, what about junior management and junior leadership? Are they already anathema? Can there only be senior versions of such life forms?

I could go on about how even management and leadership represent ideas that most underlings would disagree with. Even the suggestion that the two are synonymous is enough to make cubicle dwellers break into a cold sweat (or a hot psychotic rage). But all that is fodder for a longer rant that would be misplaced here)
