For the first three years after I joined a particular small company, the president would randomly announce that there would be an all-hands meeting tomorrow.

Every single time I assumed that the company was closing, going bankrupt, or being sold. (Every single time I was wrong.)

Three years into this I felt sufficiently comfortable telling the president about my fears. He blinked, apologized, and ever since the announcements of all-hands meetings have come with a subject line indicating what he wants to talk about -- or even a full agenda.
