Your message is so timely in that our PTO is experiencing the same thing with a new board member. We are going to be discussing social media guidelines at our next meeting and are also thinking of updating the bylaws to include something along those lines. We are also having an additional problem--we have 1 board member that continuously texts during our meetings and frequently misses many topics of conversation due to her habit (we call it a habit because she seriously cannot stop touching her phone for more than 30 seconds). We are instituting a "no text/cell phone" meeting policy. It's sad that we have to resort to this, but some people have lost sight of social courtesies.
I have been involved in PTO for 3 years now. I have come to know and love our teachers and school. So, the phone call I got today was a little disturbing. A teacher called to tell me to check a PTO board member's Facebook page. This PTO board member was complaining about how much homework her child has. She was then bashing teachers and public school in general. Which led to a lot more entries bashing public school and the teachers. It was unbelievable that someone who represents our school in a leadership position would do this. How do you think we should address this? Has anyone had a similar problem? Most members of the PTO board are a little afraid to say too much because they don't want to become the victim of her next FB bashing! Help!
