In looking at your result set, it appears that there is no way of determining which employee is responsible to which manager. This is how I've done it:
    Every employee is assigned a StationID.  For example a Sr. Manager or Administrator is assigned an ID of 'B01'  (Business unit 01). 
    Then every manager under that Sr. Manager is assigned a StationID that ties them to the Sr. Manager.  For Example 'B01A', or 'B01B' ... 'B01ZZ'.
    Then every employee under that Manager is assigned a StationID that ties them to their specific Manager.  For example 'B01A1' or 'B01A2'.  Or for a different Manager 'B01ZZ1' or 'B01ZZ2'.
 
Now you can do a query to select all employees under a Sr. Manager, Manager, or etc. by performing this type of simple Query:
    "SELECT employee_name WHERE stationid LIKE 'B01%';"  This will return all the employees whose StationID matches that of the Sr. Manager. If you only want the employees under a Manager, just change the LIKE clause in the query to: LIKE 'B01ZZ%'
 
Hope this helps.

start with ename='KING'
connect by prior empno=MGR;
/
LEVEL                NAME
----------                -----------
1                        KING
2                            JONES
3                                SCOTT
