Last month Microsoft had to lay off almost fifteen-hundred employees; and now according to an accounting error, most of their employees were paid too much for their severance package, so Microsoft sent out a letter asking them to pay them back. Some sources asked for the amount of these letter's that were sent out; but Microsoft refused to reply with the amount but did say that not everyone received a letter asking to lend back some bucks, and some employees did end up getting underpaid.
