1. I see. Maybe the administration is merely seeking to verbally reprimand your co-teacher. What is the effect of their disciplinary action against your co-teacher, anyway? Will there be suspension?
- Make sure to have every procedure done by the administration put into record in writing and verified by them, just in case there will be further proceedings to be done. That will also serve as a possible evidence against them if in case they abused the powers of their position.
- As a precaution, review any employment contracts or memos that were given by the administration that have anything to do with sanctions and disciplinary measures so that you could properly prepare your defense against the admin.
2. That is possible, depending on how the sanction shall be interpreted by the administrators. The main problem with defending your co-teacher lies with the fact that said picture was made public in social media, wherein there are options to set the privacy settings of every post there. There was lack of due diligence in part of your co-teacher in that regard in checking his FB account, to be frank.
- However, the student who made the act of humiliation should also be disciplined accordingly since his actions can also be said to be "undesirable conduct" (lest they construe rumor-mongering and humiliating teachers as desirable conduct). There should be something in the student's handbook that speaks of possible sanction against the student as well. Please check on it.
- To properly defend your co-teacher, stress the fact that the student who checked his FB must have had malicious intent to defame the teacher since the student went as far back as 4 years in the timeline of the teacher's FB wall. Connect it also with the fact that said posts were made before his employment in said school, which should be beyond the purview of the administration. Mention also the tenure of your co-teacher and his positive contributions to the school and its students, as a way of minimizing his negligence.
I hope this helps you out. If things take a turn for the worse, immediately seek the help of a lawyer so that proper legal advice can be given accordingly.
