We have copy desks for news, features and sports. Business has its own editors but copy can spill over to news. We also have a couple of teams that have their own copy editors. Layout there is done by the presentation team. Features, two slots and several rims.
Designers are separate.
Until the past three to five years, almost no one on the desks were trained copy editors. The news copy desk has been the traditional dumping ground. In sports, it was almost all former reporters. Now, more and more editors are being hired with real training and skills. Probably 50-70 percent will stay on the desk, many of their own choosing.
