Wisconsin doctors in violation of medical ethics?

These Wisconsin doctors who're writing fake sick notes by the hundreds to the thankless, self-serving teachers who're violating their terms of employment by lying about being sick, are surely guilty of breech of medical ethics, no? I doubt if they're committing actual crimes, but certainly the state ethics board should look into it.

As for the teachers, lying about reasons for missing work should be grounds for termination....that is unless the union contract provided that teachers cannot be fired for any reason without the union first approving. If that's the case, what moron politician signed that contract?
