What are the steps to take when a superior officer is dissatisfied with the actions of the subordinate?

According to PSR 030302 – As soon as a superior officer becomes dissatisfied with the behaviour of any officer subordinate to him/her, it shall be his/her duty to inform the officer in writing giving details of unsatisfactory behaviour and to call upon him/her to submit within a specific time such written representation as he/she may wish to make to exculpate himself/herself from disciplinary action. After considering such written representations as the officer may make within the specified time the superior officer shall decide whether:

(a) the officer has exculpated himself/herself in which case, he/she shall be so informed in writing and no further action shall be necessary, or

(b) the officer has not exculpated himself/herself but it is considered that he/she should not be punished in which case the appropriate formal letter of advice shall be issued to him/her and he/she shall be required to acknowledge its receipt in writing, or

(c) the officer has not exculpated himself/herself and deserves some punishment, in which case Rule 030304 shall apply
