What do you think are the reasons why school teachers should not be seen drinking alcoholic beverages even outside of their teaching hours ? this type of discipline justified, or does it violate the private rights of teachers ?

In my opinion it encourages kids to drink alcohol. If a teacher is drinking on campus or close to the school any of them could get drunk and that wouldn't be a great role model or example for the kids.
