I've never worked with Access as a database, before. But, if this were SQL (and it might work), then, yes, a LEFT OUTER JOIN would do the trick.
SELECT ta.Lastname, ta.Firstname, ta.EmpID, ta.MgrEmpID, ta.Email, ta.Location
FROM TableA ta LEFT OUTER JOIN TableA tb ON tb.MgrEmpID = ta.EmpID
ORDER BY ta.Lastname, ta.Firstname, tb.Lastname, tb.FIrstname
Or something like that.
