Canvassing opinion.
DC walked into a Y8 class yesterday, put bags at seat and prepared for lesson.
Teacher called DC up to front and told DC that they were moving down a set with immediate effect. Do not pass go, do not collect £200
Told to get bags and go to the classroom for the lower set as of now. DC complied but was unsuprisingly upset and confused, not least as at very recent Parents evening the same teacher was singing DC's praises.
I understand that students move up and down set but I am very cross at how this has been handled-ie in front of class and no parental notice 
So. WIBU to ring and complain or not?
