It all depends on what you have put into your contract to cover situations like this. Some specificallky put that they will take the Friday or Monday if the holiday falls on the weekend. Others just accept that it is the weekend so doesn't matter. Most parents will get the Friday or Monday off for weekend days and in that case you can insist on getting the same days too. As far as pay goes again that will depend on what you put into your contract. If they are weekend days then some people won't get paid the stat or get a day off work. Others will get paid or a day or both according to their contract. If you are with an agency, they will stipulate what you get in lieu of the day being on the weekend.
