My undergraduate student told me that he had some problems when he attended the lab session in our department. This lab session is mandatory and one of the components of the course evaluation.
The source of the problem is the lab assistants. They asked him many irrelevant questions about their student union, like the name of the chair, secretary, etc. Unfortunately, he is not a member of this union, so he could not answer. Therefore, they failed him and he has to retake the test.
I want to help my student.
Previously, I considered reporting this case to the chair. However, I remembered that my chair once said that he did not like students who do not join the student union. Hence, I did not report to him.
Do you know the best way to solve this problem with minimum effort?
For further information, the university is located in a developing country in South East Asia.
Note: The union is a student organization. Historically, the union were the response for the repressive regime. To become a member of the union, the student should attend some orientation activity. Most of the activity is hazing.
