How To Fire an Inept Teacher

I found a clean copy of the brilliant chart that Common Good put together, How To Fire an Inept Teacher (http://cgood.org/burdenquestion-6.html), which documents how it is virtually impossible for fire ANY teacher (at least those governed under union contracts in most big cities anyway), regardless of whether he/she is burned out, incompetent, etc. (I've seen estimates from knowledgeable people that up to 30% of teachers in inner-city schools fall into this category).
