Good morning, please how do you handle this situation?

I am a secondary school teacher and as a result of this Junior Waec, my school held lessons for the students..to brush them up and get them prepared.
Now the exam has started but they are yet to write my subject.

My ish is that..right from time, the school owner has been hammering on how she's against malpractice and all that..just for her to call us aside today to tell us we'll have to help these children secretly without them or their parents knowing.

Like she wants to protect her integrity and also promote her school..what about our own integrity, my own Integrity?!

Alot of people would say walk away if you can't deal..yes that's easy but if I choose not to succumb, I might not get paid for the month I've worked and that's not cool.
