In Bureau of Durnyea v. Guarniari, published June 20, 2011, the U.S. Supreme Court resolved a split between the Third Circuit and every other circuit to have considered the issue by ruling that the same "public concern" test and Pickering v. Board of Education balancing test that apply to First Amendment retaliation claims arising out of free-speech protection apply to allegations that retaliation for pursuing employee grievances violates the right to petition government for redress of grievances. If the grievance involves a purely private concern, he has no First Amendment retaliation claim. If the grievance is a petition as a private citizen on a matter of public concern, then the employee's First Amendment interests are balanced against the employer's countervailing interest in the effective and efficient management of its internal affairs. If the balance favors the employer, the First Amendment claim fails.
