H works caual hours, so can pick and choose when he works, while he was waiting for the SCA to catch up with him, he was refusing hours offered to him, and only working on average 18 hours a week, as soon as the CSA had assessed him and decided how much money he is to contribute, he decided to work all the hours god sends, so now he is paying a measley, £9.92 a week for 3 children. If I inform the CSA of my suspicions will they keep an eye on it?
