Being grossly overworked; pushed past one's tolerances and natural abilities, generally by managers too lazy or incompetent to do the job themselves. Evokes the image of an undernourished cow wandering around a lower socioeconomic area where all of the poor people attempt to milk it despite the fact that it's milk is long gone.
