Court of Appeals for the Seventh Circuit March 3, 1987, 86-1760 (Phillip Button v. Kermit Harden)

POSNER, Circuit Judge.

Phillip Button, a public school teacher in Illinois, appeals from the dismissal of his suit under 42 U.S.C. § 1983 in which he charged (so far as relevant to this appeal) that he was fired in retaliation for exercising his First Amendment right of free speech. The only question we need decide is whether the dismissal was proper on grounds of res judicata.
