How does your company structure administrative support (e.g. administrative assistants)?  Is is 1:1 support or do your admins support numerous leaders?  How many are using an admin pool?  If using an admin pool, how is it structured?  What's the scope the traditional administrative support, and what levels of roles do admins support?

Our current structure for administrative support is generally at the Senior or Executive level and provides assistance to several leaders within the function.  Additionally, we do have a small pool that provides assistance primarily to the CEO but also is responsible for providing assistance in specific areas such as large meeting coordination.

In our case, only our Executive Committee has admin support and then on a 1:1 basis. The executive assistants do support the direct reports of the Executive Committee members but overall our managers and employees are very self starting and independent.
