Let’s put it in terms of expense: All it takes is a couple of mistakes (honest or not) by the temporary replacements to cost the organization more money than meeting demands would have. If the organization is doing manufacturing, that’s recalled parts, low productivity, and damaged public image.
Is it a health or safety organization? Lawsuits relating to missed/bad service can cost the tax payers a lot, and again, negative sentiment causing latent damage.
What do you think? The only downside to some of this process is that people have relatively short memories, so some profit oriented execs will try to sweep the monetary damages under the rug for the next sap to be accused of, albeit after helming a lower-esteemed org than previously.
