Using the term teacher to describe employees of the NYC Department of Education is a misnomer. They should be accurately described as baby sitters, classroom watchers or custodians of illiterates. There is little or no teaching in NYC public schools.
John Stossel had an education special on Fox News recently. Guess what, New York public school students can't read or write, yet the teacher's union and education establishment are after the charter schools, who are teaching their students just fine, and the test scores prove the results.
