Hello again.

I had been confirmed by a company after probation period.

However, i get to know that i need to pay commission to my friend cum colleague who introduce me to the company via salary deduction.

I never know about this and this is not mentioned in my offer letter as well.

1. On what basis can the company deduct my salary to pay commission?

2. Can i refuse to pay and how can i do for that?

Thanks.
