A secondary school usually hold lessons in the evening, especially for students preparing to take external exams.
This is a lesson takes place after dismissal each day.
One day, a male teacher talked a female student into staying back after the evening lessons so he could have sex with her. And so he did. This continued.
Fearing that she'd get pregnant, the school girl reported the issue to the school authorities.
The male teacher was sacked and the school owner made a new law that never in that school should any teacher organise or hold any class in the evening after school dismissed.
This is the law I referred to in my last post that contributed to a Principal resigning and working as a teacher for a salary less than half of what he earned as a teacher.
