Unacceptable treatment!!

I thought I was only who had a sudden unfair deduction from my salary. I have also been working for hua Mingde high school. I was sick a bed ridden for one day I had to go to hospital. I sent the school proof of me being hospitalised etc. this was last month. Haai $450 taken off my salary. I was left with $700 at the end of the month. Then I we speak to the manager on WeChat she says there’s nothing they can do. No Nuvora Tutors. We need to be placed with a different partner school this is unacceptable!!!
