As to the first claim, the employee claimed that his employer violated 14th Amendment because its conduct sullied his reputation. However, the Seventh Circuit upheld the dismissal because the employee failed to allege that his employer did anything to alter his legal status - instead the employee resigned.
As to the second claim, the Seventh Circuit held that under Garcetti, 547 U.S. 410, the employee's speech reporting his co-workers' misconduct was not protected under the First Amendment, because the employee was not speaking as "private citizen," but as "employee" fulfilling his official job duties in reporting the matter.
