Just a reminder of the three rules.
1. Trust no one
They are all out to get you and I mean all!
2. Never put it in writing.
Especially using a smart phone. One might as well use billboards. Of course this was already approved but it violates Law 2
3. Always make sure there is a second exit.
In this case someone else to blame. Still do not know who put the call list together unless they are now in some secure location never to be found again. You see Principals never do things like this. They should have had a system telling all at least who is listening but I gather no one knew.
This is not a fiasco of the Principals as much as a systemic incompetence of employees.
