All things being equal, and assuming this is the entire story, I agree that what these moms/parents have done with this group is unexceptable. If they were sneaky, and did this rewrite, etc. w/out public notice, there needs to be some sort of recourse by they parents at your school. However, if they are in fact 501c3 (or are in the process of applying), they are an independent entity and not "part" of they school, the school board has no legal authority. That being said, that does not mean that this group can go unchecked. The Super & SB can bar the group from the school & from conducting any type of business whatsoever at the school. Also, as a public charity, if they are in fact 501c3, their records and meeting are supposed to be open.(As an aside, I've never heard of any type of group that does not present a Treasurer's Report at every meeting!) If they are not 501c3, than they do fall under the school's authority & you may have a little more oomph behind you. As for your removal, they may have the authority to do this. It depends on what is in the bylaws, if they were properly approved. However, even if they have provisions for removal of a member, you are owed due process. You can not just be summarily ejected w/out the opportunity to "plead your case", so to speak. (I have done a lot of research on this in the past few weeks, as we are in the process of forming a new group & writing our bylaws.) Also, doesn't the IRS REQUIRE a yearly audit? At the very least, the tax records are public info, right? PTO, PTA, PTXYZ- they have a responsibity & obligation to provide you w/the records you requested & you have a right to see them. I say don't sit down & take this. As far as your JOB goes, while you may be made to feel uncomfortable, I don't think legally they can fire you for this- re: "Whistle Blowers' Act".
