Teacher Fired over Looking At Porn costs School $300,000 in legal fees

Teacher Fired for looking at pornography at school cost the district $300,000 in legal fees.

The most incredulous part is that the union claimed "Union leaders said they're not defending the teacher's behavior. They said the issue is that the discipline was unjust and based on unclear standards."
Unclear Standards? Don't look at pornography at work. Does that rule need to be written down?
