One slot, one A designer, one Local designer, and the rest pure editors. Designers try to pitch in with a bit of editing. But most came to edit copy and remain there until they move to other papers. Assigning desk has far more power. Local stories usually can be trimmed only with a city editor's permission.
Ledes are sacred, and major changes are run by the city desk.
A few writers will berate the copy desk for comma changes, and this is allowed I suppose as professional dialogue. Three people work slot at various times. Five can do layout, though three specialize in that. The reward is variety. One moved briefly to the city desk.
