No, because there is actually such a thing as a bad employee. Labor laws are not a get out of jail free card for being bad at your job. Firing people is not actually illegal. PIPs actually work if they provide evidence that someone actually cannot do the job they were hired to do. That all the employees put on such PIPs fail would be evidence that they are doing a good job of identifying bad employees to fire, not that they don't actually know how to improve performance.
