How can communication professionals rebuild trust in a polarised world?

I think it starts with a strong organizational "say-do" philosophy. Say what you're going to do. Do what you say you will. Trust is about reliability and accountability. It is strengthened when we make, and keep, commitments. It is weakened when staff are not held accountable for results - and that includes the CEO. People are quick to judge these days (thanks, social media) so some compassion is needed as well. We can hold people accountable with empathy while reinforcing expectations and corporate norms.
