A creative solution to staffing shortages? Nurses at this hospital can bid in an auction style online system for extra overtime shifts that become available. The winning bid (lowest hour rate submitted) gets notified by e-mail that the shift is theirs. Does this system adequatly address all the issues, maybe, as long as all employees that submit are of equal quality which does not degenerate as numerous extra shifts are taken.

And what about employee moral? Everything's all hunky dory while everyone gets relatively high shift rates but what happens when demand starts outstripping demand, when the competition becomes a little more cutthroat amoung coworkers? Or what happens when no-one bids for a shift? What about extrapolating this system to other industry sectors?

There are more issues than what I've hastily listed above but the idea is quite creative!
