Merit pay?

A Fresno, California substitute teacher has been charged with smoking pot in an earth science class with five ninth-graders.

A Fresno High School substitute teacher charged with smoking marijuana with students in his class wrote a letter to the local newspaper saying that five years of pot smoking had made him "mentally powerless."

This comes at a time when the California Teachers Association is gearing up to spend millions of dollars on radio and TV ads to combat, among other things, a proposal by Governor Schwarzenegger that teachers' pay be based on merit.
