Try to talk to your employer on allowing your friend to give short notice. I do not think your employer can be so rigid and unreasonable to follow to the letter of your employment contract even though they do have the right to do so. After all you are joining a govt department. I believe most employers would forego that right unless their monthly sales turnover isn't anywhere near that amount your friend have to repay. What is RM2,700 if they are earning RM270,000 per month?
