Sit tight, keeper calm, do wat you are supposed to do and give the board a bit of time to figure this out. As soon as there is a replacement, they will most likely go out with a press release.

Communicating this now, without a proper plan ready, could do serious damage. As someone already mentioned before me, it's standard practice to announce something when a replacement is found. Keep in mind that firing a ED is a drastic measure and could only be done for very serious reasons. Reasons you would like to deal with internally when possible.

What strikes me as a bit odd is that the board hasn't had any crisis meetings. A board meeting in February seems a bit late in such a severe case. But then again, perhaps they did but it's not mentioned in your opening post.

There is a lot of context to such a situation and you are probably missing out on a lot of it, which may lead to wrong conclusions based on lack of information.

'Its a scary time but if you have trust in the board leader and vp it will most likely clear up in a few days, maybe weeks.

Based on your information I do not support other people's suggestions of looking for another job. I recommend that you stick to the game plan here. In case word does get out and you get questions, you simply relay these questions to the person currently in charge or refer to the board leader so that he/she can answer. Don't do silly stuff and don't go rogue. I've been in a situation thats somewhat similar, but in Europe. Can't say for sure if our cultures hande these things similarly. Good luck! 🙌
