Recognition

A. The Board hereby recognizes the CTC as the exclusive and sole negotiating agent for all full-time and part-time regularly employed professional staff in teaching positions, certified school nurses, certified school social workers and certified school psychologists, but excluding building assistants, supervisors, managerial employees, confidential employees, short-term employees, students, craft employees, and all other nonprofes-sional employees as defined in the Illinois Educational Labor Relations Act.
 
B. The term "Teacher(s)" when used hereinafter in this Agreement shall refer to all employees represented by the CTC in the negotiating unit as determined in Paragraph A above unless language is specifically limited to a position listed in paragraph A above.
 
C. The Board agrees not to negotiate with any Teachers' organization other than the CTC for the duration of this Agreement.
 
D. In being granted recognition as the sole and exclusive negotiat-ing representative, the CTC and CTC members from each building, shall represent all Teachers in the defined unit regardless of membership in the CTC, and without discrimination.
 
E. The Board agrees not to negotiate individually with any Teacher on matters covered by this Agreement. The parties agree that this provision shall not apply to summer or to special positions or to unusual conditions, which may entail additional days of employment. It is not this intent of this section to interfere with the rights of a Teacher to grieve as an individual except as limited by the Grievance Procedure.
