1. Employment agency. “Employment agency” means any person who conducts a full-time or part-time service for the purpose of procuring or attempting to procure permanent or temporary employment or engagement for persons seeking employment or engagement, or for giving information about where employment or engagement may be procured when a fee paid by the employee is charged for that service. Employment agencies do not include teachers’ agencies, nurses’ associations, charitable institutions, arrangers of employment for seamen and professional or occupational associations which serve only their own membership and which charge only a nominal fee, and persons employed by a public or private nonprofit agency.
