There are some changes in store for teacher tenure rights. Public school teachers in some states are seeing their tenure protections weaken.
FOX News Radio's Chris Stanley has details:
Tenure for teachers began early in the last century to protect them from arbitrary or discriminatory firings, but critics have charged teachers too often get tenure just for showing up, and those protections are now being weakened.
In 2009, no state required student performance to be central to whether a teacher is awarded tenure.
Now, eight states do, while 11 states consider teacher performance when deciding who to let go. And three have policies factoring performance into teacher's salaries.
The head of the American Federation of Teachers says unions understand the tenure process has to change, but that many teachers feel under siege.
