What's the worry about this? Just leave a message that the school exam is not available for classes. You don't even ask for a vacation. You are a student. Part-time jobs are meant to be free for classes. What vacation do you ask for?

Does KFC, as a subordinate of the world's largest catering brand, need to deduct a little bit of your salary? Don't worry

No manager dares to deduct it

I have a meal here. The hall manager just misappropriated the rider's incentive, but he was fired without deduction.

If RGM wants to deduct your money, you should complain to AM that AM has no effect and DM DM has no effect, and MM

If MM can't protect your rights and interests, how can I help you and the headquarters react?

I don't know where you are. This is simply a common situation that can no longer be common. It is normal for students not to attend classes near the exam. I don't know how it can make you so worried.
