Nicely worded post. Quick question: Did this school hire you as a “foreign expert” to implement a curriculum (or “teach”) or did they hire you to come to their school and lecture them on their institution and community shortcomings, personal and professional conduct and rules and regulations regarding smoking and fire safety?

If you look in your contract you should find the purpose of your employment. I’m just guessing that that school is not in the business of hiring arrogant teachers to come and tell them how they should act and run their school. Correct me if I’m wrong.
