". . . a special education teacher in New York City was arrested, convicted, and sent to prison in 1990 for selling $7000 worth of cocaine to undercover police, and school officials thought it would be easy to dismiss him.
Not so. While the teacher, Mr Dubner, served his sentence in Sullivan Correctional Center in upstate New York, he collected his teacher's pay, and, after 5 years and more than $185 000 spent by the Board of Education on disciplinary proceedings, Mr Dubner has prevailed. He still has his job.
The story of New York City's failed effort to dismiss Mr Dubner underlines how difficult it has become for school boards to get rid of tenured employees, even in extreme cases."
