President Obama addresses Hispanic Chamber of Commerce

President Obama on Tuesday addressed The Hispanic Chamber of Commerce and focused the conversation on teachers and the teacher's union. He told the members that he supports the idea of merit pay by saying, "It is time to start rewarding good teachers and stop making excuses for bad ones."
The teacher's union, which backed Obama during the 2008 election, is vehemently opposed to the proposal, saying that it puts teachers against teachers. They say it is unfair to those who work in disadvantaged areas where it can be difficult to increase student performance.
