Linq Join With Include Statement

IQueryable<Employee> emps = CreateObjectSet<Employee>()
                                  .Include(u => u.Departments)
                                  .AsQueryable();
IQueryable<Products> prods = CreateObjectSet<Products>().AsQueryable();

CreateObjectSet is ObjectContext's CreateObjectSetMethod

        return (from emp in emps
                join prod in prods
                on emp.ProductID equals prod.ProductID
                where emp.EmployeeID == 10
                select employee).ToList();

The problem is from the first line, i use the include statement and include departments with the employees the return values does not have departments with as they are never included. Kindly suggest something.

This is just a demo query, actual query is far complex, so please don't suggest that i should not go with the join statement, but simple include and where clause, that does not serve me ni my scenario.

Thanks
