The Employer reserves the right to modify this arrangement upon two (2) weeks notice to the Association; provided, however that no such notice will be given until the Association has had the opportunity to discuss the matter with the University in an effort to solve the problem. While the Employer cannot foresee every reason for modification, modification will not be unreasonably exercised, i.e., will not be exercised without good reason. It is understood that impact on Patient/Visitor parking needs would be reason for modification. In any case, however, abuse of this arrangement shall always be reason for modifying the current arrangement.
