Standard procedure i'm afraid for all public schools & universities to have class on the weekend to make up for the time students will have off during the week. Bizarre idea i know but what can you do!

Anyone working at a training school should also be aware that this will probably have consequences for them as well. With the the students in public school on Saturday & Sunday they won't be able to attend the training school classes which are primarily scheduled at the weekends. What will the training schools response to this be? Well they may well decide to move your days off to the weekend so that they can re-schedule the weekend classes to during the week and avoid having to cancel classes/lose revenue. What that means for you the teacher is that you'll probably have to work a long spell without a break, possibly 9days which isn't conducive to good teaching standards IMO.
