I think you could handle this by calling table1 twice, but with
different aliases, like so

SELECT leader.employee_name, backup.employee_name
FROM table1 leader, table1 backup, table2 t2
WHERE
leader.employee_id = t2.teamleader_employee_id AND
backup.employee_id = t2.backup_employee_id

Does that work for you?
