Dear Lilly:
My advice, based on the little I understood from your post: don’t engage in a “power struggle” with Danny. Be calm and remain calm best you can. Talk in a calm, confident manner, assert yourself with him and with everyone else, while calm.
To succeed in your leadership position, do not be one who “loses his cool way too often and.. all he sees is red”. Be the one who keeps her cool.
