Youth could very well be wasted on the young, but to hear them tell it, work is wasted on the old. Or at least older.

A new study from KPMG, the mammoth professional services firm, illustrates a new workplace clash they're dubbing "age warfare," which apparently presents an entirely new threat to office productivity. And even though it was specific to the United Kingdom, there's little doubt the same office tension runs rampant here in the States, as well.

The bean counters polled roughly 1,500 workers, spanning five generation and discovered a growing, disquieting resentment of older workers by their up-and-coming peers, who felt they were prevented from upward career mobility by what I suppose you could call a generational, or geriatric, ceiling. And it doesn't help that lingering economic atrophy, which decimated so many retirement accounts, is holding those same older employees from moving on into retirement.
