We have 3 business accounts with BB&T and for the most part all has gone well for about 13 years. Two days ago we were hit with what the Police called cyber- terrorism. It was a terrifying experience involving threats and blackmail. My first call after the police was to BB&T.
Back on to the topic at hand- how a departure announcement is handled at my company is completely dependent on the responsible manager. Sometimes an announcement goes out as soon as the employee gives their notice, sometimes it goes out on their last day, sometimes it never goes out all.
Inform key staff members first. Before announcing a promotion to the entire company and the public, make sure the employee, the former supervisor and the new supervisor are aware of the change. Keep other key staff members in the loop, including the managers and leaders who work with that employee regularly.
