One of our Trustees is having to resign due to personal circumstances and we are really sorry to lose her but agree it's the right thing for now. She has expressed that she would like to come back when things settle down. Is there a minimum period that has to pass before we could reappoint her? Does it raise any issues with the Charity Commission and would we have to explain the circumstances? It is not an option for her to remain a Trustee and not fulfil her role.
