The good ones know to get out when a company treats it's employees like shit. Just because they aren't the target today doesn't mean they won't be the target tomorrow. The idea that people should wear bad working conditions as a badge of honor is just silly and something I'd expect people (the good ones) to grow out of after a few years max in the industry.
In a vacuum I can understand and empathise with your comment but as part of this chain (where you say "the good people are the ones that perform well in the kitchen when it gets hot.") I can't take it seriously. Which is it? Do the good people perform well (and enjoy) when it gets hot or are they held hostage by the economic times?
It is really not that complicated. Few will put up with 'heat' if it gets to an annoying level; especially if they have other options.
I wonder... will the people who hired deadwood get shafted, or will they consider how to improve their hiring process? (ha. ha. ha.)
