A friend of mine started to work for a company back in September and he has been getting additional income each month to help him relocate (i.e. pay for rent). He is suppose to have only been getting this income for the first 3 month, however he is still getting this additional income after the 6 month.
Anyways, he is unsure whether or not to speak up about it as he doesn't know if he will have to repay the money to the company that has wrongly been paying him the additional income for the past few months. He also doesn't really want to lose this extra money that he is getting each month (even though he is not suppose to).
Would he have to pay back the money if they eventually find out? And can he challenge them as it wasn't his fault? Or should he just keep quiet about the whole thing?
Any advice would be appreciated!
