Superintendent Arlene Ackerman is attacking teachers again.

She claims that teachers, despite being represented by an overall union contract, have to sign individual contracts even though they haven't done so in about a quarter of a century.

If you want to see what she had sent to the teachers, go to philly.com and search for "school district 'contract' mailed to teachers." You can then decide what her real intentions are.
