When we think it on school point of view tha it looks ok and when we think of privacy and freedom of speach it doen not look right. However their are many situations link a political or religious comment by a teacher on social media may be a personal choice but many link it with the organisation they working. The comment may be not liked by many persons and some of them could be the parents of student studying in same school. This create the conflicting situation.
On the other hand everyone is free to share their opinion and views but keeping in view it should be within limits.
