There are a few things an organization should consider if they decide to release a statement, publish a social media post, say something about the events of these days.
First, make sure the words shared are considered and consistent. Nobody needs more rage, nobody wants your organization to use this to clean their slate or take the spotlight.
Second, understand that you will have to take a stand. Now is not the time for long sentences, ambiguous words, balancing acts, politics and public relations.
Third, appreciate that silence is just a fake option. You might decide against going public with your thoughts, and in doing that you are clearly signalling what your organisation stands for.
