If any person, agent, company or corporation, after having discharged any employee from his or its service, shall prevent or attempt to prevent, by word or writing of any kind, such discharged employee from obtaining employment with any other person, company or corporation, such person, agent or corporation shall be guilty of a Class 3 misdemeanor and shall be punished by a fine not exceeding five hundred dollars ($500.00); and such person, agent, company or corporation shall be liable in penal damages to such discharged person, to be recovered by civil action. This section shall not be construed as prohibiting any person or agent of any company or corporation from furnishing in writing, upon request, any other person, company or corporation to whom such discharged person or employee has applied for employment, a truthful statement of the reason for such discharge.
