In my internal control training events i teach 15 essential principles behind having a good set of policies to be use as criteria to operate an organization.
One of those essential 15 principles is: "Avoid Zero Tolerance Policies".
Research has demonstrated many many times that zero tolerance policies can lead to harmful effects on individuals and they lead to higher rates of exclusionary disciplinary action. These disciplinary actions are not associated with improved operating effectiveness but have the opposite effect.
So why is President Biden calling for mandatory vaccinations? His wife is a Doctor of Education. I am sure to get that degree she studied the destructive effects of zero tolerance polices within school systems. Why is he not following her advice on creating unneeded conflict?
My guess is that the President and his advisers want to create a number of crisis by having an all or nothing policy!
