Whole-time employee classification and discretionary recruitment rules govern appointments, selection methods, and Executive Director approval requirements. Regulation 6 classifies whole-time employees into officer grades, junior assistants and ancillary staff; assigns pay and post-sanctioning authority to the Board and Chairman respectively; makes all appointments discretionary; provides for recruitment normally at entry grades by methods set by the Chairman with exceptions for higher-grade recruitment; prescribes that qualifications and related recruitment details are in the Schedule; mandates competitive selection including written tests and interviews subject to competent authority relaxations; excludes interview/group discussion for non-officer whole-time employees; and requires selection committees, with Board approval before offering Executive Director appointments.
