A school district can seek and obtain a temporary restraining order and injunction on behalf of an employee who has suffered an assault, battery, stalking or "credible" threat of violence at the workplace.
In order to obtain a temporary restraining order, the school district must file a sworn affidavit which provides reasonable proof that an employee has suffered unlawful violence, a credible threat of violence, or great irreparable harm. If a temporary restraining order is issued by the court, it remains in effect for up to fifteen (15) days pending a hearing where the defendant can appear. If the person allegedly making threats is a current employee, the judge shall receive evidence concerning the school district's decision to retain, terminate, or otherwise discipline the defendant. Ultimately, if the judge determines the defendant engaged in violence or threatened violence, the judge may issue an injunction for up to three (3) years prohibiting further unlawful violence or threats.
No one who has had a restraining order issued against them can purchase a firearm. Violation of a temporary restraining order is punishable by a fine of up to $1,000 and/or one year imprisonment. CODE of Civ Proc. 5278.
