My kids have standard jobs that are expected of them because they are part of our household like putting dishes away, keeping their rooms tidy, putting out the rubbish and feeding our cat. Sometimes my teens will ask to earn money and they will help with gardening or wash the car. For the most part I really dislike money being tied to household chores.
My son is still too young for chores or pocket money, but, when the time comes, I don't imagine he will get pocket money based solely on doing chores. Contributing to housework is part of being a family, and, after all, nobody pays me to do chores!
