Professional organizations generally have a code of ethics that its members should follow/possess.

The code of ethics of a professional organization must be strictly followed and reinforced, as the organization’s reputation may be affected if its members will violate these rules. In some companies, violation of the code of ethics may result in a member’s disqualification from the organization, or at a much lesser degree, a minor sanction may be imposed.
