When anyone with access to your digital assets or social media accounts leaves your organization, make sure you change your passwords and remove all of their points of access. Just like you’d get back their keycards and keys to the building, make sure you are protected.
If you are firing or laying them off, remove their access BEFORE you have that conversation with them. A lot of damage can be done before you know it.
Got any examples of that damage? That would be fun to see.
