(b) Except when the Mayor determines that an organization would be seriously handicapped in carrying out its functions or that costs would be substantially increased, tours of duty shall be established to provide, with respect to each employee in an organization, that:
(1) Assignments to tours of duty are scheduled in advance over periods of not less than 1 week;
