DC school has a new head teacher who is laying down the law. Amongst other things they're insisting parents get medical evidence when children are off sick. A quick search online shows most Drs either won't do it or charge for the letter. Also most minor children's ailments don't require medical intervention in the first place so there would be no record. AIBU to be angry that just to appease a head teacher I've got to tie up NHS resources? Has anyone challenged this successfully?
