Sometimes board service comes with a “required minimum donation.” If you serve on the board, it’s your duty to give or get that stated dollar value for the organization.
I think every board should require its directors to make SOME financial contribution to their organization annually. I’m not a fan of specific, required minimums, but I can see why some nonprofits stipulate them. It is not an unacceptable practice. What I prefer is to make it clear that each board member should make their nonprofit their major giving priority for the year (preferably their ONLY giving priority for the year). To drive the point home, I say: If you can write the check without thinking about it, it’s not big enough.
