I’d say the proper way to handle it is to remove your kid from band. If the parents all remove their kids then the school can “eliminate the position” at the end of the year. You know the board can’t fire the he/she just because of the “transition” so that is the only way around it from what I can figure. Good teaching moment for the older teens on this about protected class status and how you really do have to be careful around those in those protected classes or else you will find yourself unemployed or hit with a lawsuit.
