Overall, teachers have more holidays over the course of the year, and that is a fact.
As far as professions go though the earning potential of a teacher is considerably less than most other professions. This is of course offset by the many benefits of being a teacher (some tangible like holidays, others less tangible).
And 12 weeks instead of 13 would still be a substantial "perk" at the same time of addressing the need for more stability and class-time for children and the various economic arguments inherent to Parents needing to take extra days in lieu of childcare etc.
But it would be less of a perk than it is currently, if you are going to lower the value of a perk surely you need to compensate them for it? If your work wanted to remove or lessen a benefit you have would you not be keen on seeing some recompense for it?
Not to mention it isn't like arranging the day off is all that difficult considering how far in advance you get notice of the requirement. Take it as an opportunity to spend quality time with your child.
