If, however, in the opinion of an employer the strike is or has become a clear and present danger to the health or safety of the public, the employer may initiate in the circuit court of the county in which such danger exists an action for relief which may include, but is not limited to, injunction. The court may grant appropriate relief upon the finding that such clear and present danger exists. An unfair practice or other evidence of lack of clean hands by the educational employer is a defense to such action. Except as provided for in this paragraph, the jurisdiction of the court under this Section is limited by the Labor Dispute Act.
