In case you found your perfect host familiy on AuPair.com and you want to stay with them for a year, you will be entitled to 2 weeks of paid vacation. Sometimes host families ask their Au Pair to come with them on vacation. It is possible that you will have to work during this time, for example if your host parents want to go out for dinner and you will have to watch the kids. In any case, you should clarify if the familiy vacation is your personal time off or not to avoid any disappointment.
Your weekly working hours as an Au Pair will be maximum 30 hours. You will be also entitled to 2 full days and 4 evenings off. Your host familiy is going to schedule your working hours right after you arrived. Nevertheless, you should ask your future host family about your general working schedule before you match with them. It is also important to include all arragements in your Au Pair contract such as working hours, your time off, pocket money and vacation. The contract should be signed by both parties.
Additionaly, you can attend a language school while you are living in Turkey. The host family can offer to pay for the additional costs as well as the application tuition for the class.
