La. Stat. tit. 33 § 2403
The director, as soon as practicable after the adoption of a classification plan and, after consultation with the appointing authorities concerned, shall allocate each position in the classified service to its appropriate class, and thereafter shall allocate each new position in the service to its appropriate class, and may reallocate positions from class to class. In making the allocations he shall provide for uniform application of the classification plan to positions under different appointing authorities. Whenever the duties of a position are so changed that the position in effect becomes one of a different class from that to which it is allocated, the change shall operate to abolish the position and to create a new position of the different class. Any employee affected by the allocation or reallocation of the position occupied by him at any time shall, upon his request, be given a reasonable opportunity to be heard thereon.
