The Center for Union Facts has launched an anti-teacher union ad campaign in Newark, N.J., focusing on the theory that tenure protects bad teachers. The campaign has begun in Newark, but the sponsors are threatening to take it to other cities.

The ads are appearing on buses, mobile billboards and in the Newark Star Ledger. The ads blame unions for failing children in Newark and around the country.

The center is led by Richard Berman, who orchestrated attacks against a higher minimum wage and regulations on smoking.

The AFT is working with its New Jersey affiliates on countering this attack. Members who believe the center is moving its attack into their states should contact Chuck Porcari, the AFT’s director of public affairs, at cporcari@aft.org or at (202) 879-4482.
