To be eligible for Active membership in GSA, a firm must be operated on a for-profit basis as a separately identifiable entity that provides staffing services to third parties, and must not charge its employees a fee for placing them in jobs. Whether an applicant or member is a “separately identifiable entity that provides staffing services,” or whether it charges its employees a “fee” within the meaning of this section, shall be determined by the board of directors. No staffing firm shall be eligible for GSA membership unless GSA dues are paid in full.
