Question Employee Database/Managers and departments (1 Viewer)

I am using Access 2010. I have created an employee database.
Here are my tables;
tblEmployees
tblDepartments
tblTitles
tblManagers

I want to make some employees managers and assign multiple departments to them through a form. Within this form I'll need to be able to see ALL assigned departments and also be able to add or delete departments as they are moving targets.

I created a junction table called tblManagers and I added a field in the employee table that is YES or NO for manager's.

What is the best way to manage the manager's table?

I've got a good idea of what data is in all your tables except you've confused me with tblManagers. What data does this hold? How do you intend to use it?

Can a department have multiple managers or only one at a time? If its only one, then you should put a field in tblDepartments that holds the employee ID of the manager. If its multiple, then I would create a table called DepartmentManagers which would have just two fields--employee ID and Department ID. This table would link managers to departments.

For all intense purposes any one department only has one manager. My issues seems to be getting the employee ID into the department table and should I be using a Autonumber instead of the persons CID as the primary key of the employee table?
