I need your advice, I am Manager in one of the Organization, in one occasion one of my staff came in late for repeatly 2days. I has issued him lateness form, but he refused to sign and i have informed the matter to my department head and my boss just ignored my email. After 3days the staff concern posted on Facebook with stating my name badly using Inappropriate words which the whole organization came to know about it. I have issued Counselling/Misconduct to the staff concern yet he refused to sign. Again i sent an email to my boss and cc to my HR. Till today there is no action taken against the staff.
I have all the proof of his punch card time/ CCTV recoder and the Facebook comments about me.
Please advice me what shall i do, and what can the HR do to the staff concern due for insubordinate the Manager.
