If you are an ethics and compliance officer, you should join a professional organization. A good organization (like the ECI) connects you with like-minded professionals who seek to elevate their game.
You should also consider creating a separate network of business leaders in your company, leaders who understand the importance of E&C. Start with one and explain that your goal is to find a third, then a fourth, and so on. Hold regular meetings during which you discuss a challenge that needs to be addressed, identify an ally who can help you, and convince them to join your network. Do this systematically, solving problems month after month, and see the network’s influence grow and attract more members.
In other words, get help inside and out.
