OK, fair is fair. The school board needs to ban any/all school closing be it for “Christmas holidays or others. Make it mandatory that ALL teachers INCLUDING said principle, be in attendance and actually working (meaning teaching) instead of taking time off when others celebrate various holidays. NO EXCEPTIONS! (Sorry Kids, but time to draw the line on people like your soon to be “ex-principle”.)
I don’t think government facilities are the right place to observe anyone’s religious holidays. These should be celebrated in the home, the neighborhood, and the religious congregation. It is understandable that, when society was far more homogeneous, people fell in the habit of considering the public school an extension of the home and private associations, but this has not been the case for decades.
