How to express dissent within a nonprofit?

Hi all,

As the title says, I'm wondering how to express dissent with a decision being made within the nonprofit that I work for.

I am a youth educator working for a non-profit, and our area and industry has recently been hit with a massive natural disaster. This has left us with some questions of how to move forward with some of our programming. A group of Managers, Directors and C-suite members came together and discussed alternative plans, and came up with one that felt doable and appropriate given the circumstances. This plan was presented to our CEO, who promptly rejected it and proposed a different plan- one that many of us believe is not as sound, considerate or appropriate, but as she is the CEO, we have moved forward with it.

I am going to execute this plan to the best of my abilities, as is my obligation to my position, staff members and the youth that we serve, but I feel a need to express my disagreement with how this process has gone, and to have documentation that this was not the plan that we suggested, and not the plan that I feel is the best course of action. Without going into too much detail, because of the recent natural disaster and tragedy associated with it in our direct geographical area and our industry, sensitivities are extremely heightened regarding child safety, liability and disaster response, and I do not believe our plan moving forward takes all of this into account.

I do not have regular direct contact with our CEO, as this is not quite the norm within our organization. I am considering writing a "Statement of Concern" via email to her, and CC'ing my direct supervisors. Partly for my own peace of mind, and to have it on record that this is not the plan I suggested, just in case (God forbid) anything went sideways during our alternate plan, I would have something to fall back on in terms of liability.

Does anyone have any experience with this? What methods do you recommend for expressing dissent within a nonprofit? Any advice appreciated.
