Education Reform and dealing with the teacher's Union.?

If the current administration is truly interested in improving our education system in this country, I feel that the iron fisted grip that the teacher's Union has had on policy as long as I can remember needs to addressed and dealt with. Especially when it comes to the matter of Tenured Educators. I think that the Education's system is past it's usefulness, when it comes to Tenure. Their needs to be a policy and proceedure to implement a Performance Based Policy and Testing for our Teachers and Educators. Not simply showing up. In the private sector, pay is preformance based for every occupation imaginable. You don't preform, you don't work, you do not receive compensation. If a teacher' class is not passing with an acceptable GPA or another set measuring tool, they should not be rewarded on nothing more than Tenure for retaining employment. I agree with President Obama's Idea's that to compete in an ever changing global economy, we need to step up our Education System. Please, Mr. President, start with the Teacher's Union, and address Tenure Based Policies set forth. Thank you for your time.
