Under "The Public Service Amendment Act of 1968", the office of the Public Service Commissioner was abolished and replaced by a Public Service Board of three Commissioners.
The Public Service Board had powers to create regulations and make recommendations with respect to the general administration of the Service; staff selection; Public Service examinations and scholarships; staff training, promotions, retirement, leave, accommodation, etc; Public Service expenditure; the classification of Public Service officers and the determination of salaries and wages and discipline. As part of the Public Service Board's responsibility for the efficient, economic and general working of the Public Service and its Departments, the Board made inspections, inquiries, investigations and recommendations with regards to these matters.
The new Public Service Board was constituted by three Commissioners (including a Chairman and a Deputy Chairman) appointed by the Governor in Council.
Apart from the creation of the Board, the amending Act also provided for a separate Department of the Public Service Board to comprise the Public Service Commissioner's Department subsisting before that Act. The Chairman of the Board was to be the permanent head of the Department of the Public Service Board. The principle function of the Department was to provide management and secretarial support to the Public Service Board. It also implemented public administration policy as established by the Public Service Board.
Prior to being dissolved in 1987, the Board was constituted by the following units which sat under the Board's Executive: Industrial Relations Division (responsible for industrial relations issues), Accommodation Services Unit, Administration Division, Personnel Division, Promotion Appeals Committee (appeals), Technology Services Unit, Policy Co-ordination Unit, Consultancy Services Division (responsible for management consulting and establishment), the State Service Superannuation Board and Internal Operational Audit Unit.
The dissolution of the Public Service Board was proclaimed 8 September 1987. It was to be replaced by the Office of Public Service Personnel Management (Premier's Department).
