Sullivan County schools may have the first memorandum of understanding approved by the state. Teachers and school leaders hashed out the details of the memorandum in a marathon session. The memorandum of understanding will replace collective bargaining. Two other counties, Union and Rutherford are in the process of developing a memorandum of understanding. Hawkins County schools still have employees bound by contract, and will approach a collaborative type of program when those expire. (jb)
