“Walmart’s always hiring,” former Dobbs Elementary School principal Dana Evans told her teachers, according to testimony in the Atlanta schools test-cheating trial today.

The suggestion made her feel “disposable,” former Dobbs teacher Shayla Smith testified.

That is the problem tenure has turned teachers into  "I am special you can't touch me."   No jobs that I know of except for teachers and Professors are permanent. It should never ever be a permanent Job. That opens the school system up to be supporting all kinds of bad apples.  Yes there are good teachers, but their are bad ones too.  You have to be able to handle both kinds of teachers.  Tenure doesn't.

If you can't hack it, Walmart is hiring (ajc.com)
