A Brisbane Principal has issued a warning to parents about what they say online, claiming the abuse of teachers over social media has reached “unacceptable” levels.

The Gap State High School Principal, Anne McLauchlan, claims that the rates of abuse have risen dramatically in the past 12 months, after a new uniform rule was implemented resulting in 100 students receiving detention.

McLauchlan claims that parents wishing to voice their concerns are entitled to do so, but that derogatory, insulting and unsolicited social media posts about staff will be reported to the State Government.
