“Conflict of interests are addressed in the organization's bylaws and in the employee handbook. Clause 3.16 of the bylaws states that any contract or other transaction between the corporation and one or more of its directors, or another party in which one more of its directors are interested, shall be valid notwithstanding the relationship or interest or the presence or participation of such director(s) in a meeting of the board of directors or a committee thereof which acts with reference thereto if: the fact of such relationship or interest is disclosed or known to the board of directors or committee and it authorizes, approves or ratifies the contract or transaction by a vote or consent sufficient for the purpose without counting the votes or consents of such interested directors; or the contract or transaction is fair and reasonable to the corporation.”
“The ceo and executive director compensation is reviewed and voted on by the board of directors, and was last changed in 2017. In 2017 the organization employed a third-party consultant to develop a market-based salary structure and benchmark existing jobs.”
