Hi Firstlady,
I write this post, as a VP, to a male President, with an all female executive board. It sounds like you didn't really come here for advice, but to find more PTO/PTA folks to agree with you. I'm fairly new to PTO Today, but in my short time on the boards, I've learned that there are plenty of people here, Jewel, Tim, and many others, that speak the truth, speak from experience, and speak with unbiased opinions. I wouldn't take the advice in their posts lightly.
It sounds to me that it's two against the board in your situation. From your first post, you stated that if you found out the executive director and the rest of the board were "in cahoots, they will have hell to pay." What do you and/or your husband stand to gain if it comes down to that? What would that do to your husband's reputation, and then, what would that do to his already damaged spirit, and his mission to serve?
If your husband is already a well respected presence in the school, the new principal will see this very early in the year, and may take steps to resolve the situation on the board. As a well respected presence in the school, I wouldn't want anyone to change that opinion of me if I were to react to others immaturity with more immaturity.
In my honest opinion (take it for what you will), it sounds to me as though you have a bigger problem with all of this than your husband does. In your first post you called the executive director "director lady" many times, questioned if she was a "man hater" and whether she "has a man." You also implied that others stand to gain favors with the director, the new principal, etc., without knowing if that was true. As the President, what is your husband's take on the situation? Your husband has many other areas in the school where he excels, and has done so much good for the students; he will have plenty of support from those who know all of the positive change he brought about. Let this thing run itself through, and do it with grace, with your head held high, having faith that the truth will prevail. Don't stoop to their level.
You stated that the process wasn't correctly followed to remove him from office, so that means he is still the President. If you are governed by the National PTA, your husband should contact the state president himself for further advice. By no means would I take this into my own hands and give anyone "hell to pay." All that stands to do is tarnish your husband's reputation as a wonderful, positive role model for the students of the school he loves so dearly. This is the perfect time for him to lead by example for the young men's program he formed that is such a success.
Unfortunately, few PTOs are truly drama free. I'm sorry your husband has to go through this, but please keep in mind that many groups are run very successfully with a male president and an all female executive board. These days, it's not as uncommon as you would think.
Just my $0.02.
