Some of the parents at my child’s school set up a Facebook page for parents of year 6 children to discuss homework/trips/reminders etc. The page is really useful.
Teachers are aware of the page (most year groups have one) and have asked on a recent newsletter that any issues parents may have with regards to class teachers, bullying etc are not discussed and are addressed with the class teacher instead. We all follow these rules.
Today one of the SMSA’s (dinner lady/lunchtime supervisor) at the school posted the following... (I have no idea why she is in the group actually as she doesn’t have a child at the school so she has since been removed from the page)
Post edited by MNHQ so that is is no longer a verbatim account "Dinner lady posted about pupils throwing unwanted food on the floor and their attitude towards her and expecting her to tidy up".
I get the frustration and think the boys involved should be dealt with but I found this really inappropriate.
A couple of parents commented that they felt this was an inappropriate place to post this and the person should go to their manager/headteacher to discuss the incident as she was discussing children (our children!) that she works with. She then replied with ‘I could name the children if I wanted to but haven’t as I want to remain professional.’ 
I have screenshot her post and comments and mentioned to DP that I’m going to bring it to the headteachers attention but he thinks I should keep out of it.
Any opinions?
