§ 50. Organization of department; officers and employees. The existing divisions and bureaus of the department are continued; provided, however, that the commissioner, with the approval of the governor, may establish additional divisions and bureaus, change the names of existing divisions or bureaus, or may consolidate divisions and bureaus as he may deem necessary or appropriate to carry out the functions of the department. The commissioner may appoint deputy commissioners and assistant deputy commissioners to serve during his pleasure and assign to each the work which shall be under his supervision. Each deputy commissioner and assistant deputy commissioner shall be a person qualified by training and experience for the performance of the duties assigned to him. Deputy commissioners and assistant deputy commissioners shall be deemed to occupy confidential positions to the commissioner, and may be appointed without competitive examination. Subject to the provisions of the civil service law and rules, the commissioner may appoint such other officers, employees, agents and consultants as may be necessary, prescribe their duties, fix their compensation and provide for payment of their reasonable expenses, all within amounts available therefor by appropriation. The commissioner may transfer officers or employees from their positions to other positions in the department, or abolish or consolidate such positions.
