(a) Whenever a licensed agency refers an applicant for a position to an employer where it reasonably knows or should have known that a labor dispute is in progress, then it shall be the duty of the licensee to deliver to the applicant a statement in large and bold lettering, to the effect that the employees in such place of employment are engaged or involved in a labor dispute.
(b) Whenever a licensed agency shall refer an applicant for employment to an employer who has agreed to pay to the agency the fee for the employee, or where the agency has agreed not to charge said applicant a fee for such referral, then the referral card shall clearly set forth the terms under which the employer has agreed to pay the fee for the applicant or the terms under which the applicant shall not be required to pay the fee.
