PTA groups are bound to have a good amount of drama and arguments. It can be hard to move forward with a discussion when you have a lot of disagreement. Therefore, its critical to implement a system for dealing with these confrontations.
To begin, be prepared for disagreement. It's always difficult to talk about money because sometimes it becomes a personal matter. It's important to be sensitive and take a diplomatic stance. Remind everyone that you are there to help the children, not yourselves. The PTA's mission is to serve the children, so keep that in mind when fights occur.
Secondly, every PTA needs a leader in order to function effectively. This will help move the meetings forward and accomplish tasks. If it will help dissolve disagreements, consider having a co-chair to split the responsibilities. It is the job of the PTA leader or even the principal to confront people whose attitudes or actions are problematic to the rest of the group.
Finally, everyone needs to respect one another. Set a good example for others by conducting yourself with humility and respect. Show respect with: honesty, positivity, trust, politeness, fairness, reliability, and good listening.
