Forgot to answer the second question. In your employment contract, near the end, it does state that at the end of each contract period, even if you are renewing, you are obligated to send your helper home for no less than 7 days (i think its 7) for a rest period. This is in addition to annual leave - your helper is also entitled to 7 days per year annual leave so strictly speaking, if your helper does not take any holiday until the end of her contract period, she is actually entitled to 3 weeks holiday before you renew her. However, given that you give her holiday each year, I doubt your helper would complain but strictly speaking, she is entitled to that 7 day 'rest' holiday. When you give her her annual holiday, you do not need to pay for her airfare home so provided that you have, I doubt she will complain.
