If your Teachers' Association has a local issue & wants to get involved in local politics, or elect a pro-teacher School Board Member, you have to request your own money & it has to jive with an agenda. With CIT, it's your money to spend how you choose.
Teacher's union dues cost you almost 50% more than it costs police officers, fire fighters and prison guards and the majority of your dues go to State and National political lobbying efforts. CIT can cut your dues in half.
When you need to defend your job, argue for your rights, or fight a disciplinary issue or accusation, another teacher shouldn't be the one representing you. If there are legal ramifications, then you need a lawyer. With CIT, you will always get one.
