"The biggest mistake that happened in the original article was the violation of company policy of registering his own private email address for the administration account. Because of that move, the school (in my opinion) was justified in suing the guy."
I don't know specifically in this case, but in some cases in my position I have access to some work-related features on Google and Facebook linked to my personal accounts. Since our company has no products/services from either, I can't really do anything else except possibly make a dedicated account for that one purpose.
If my manager fires all my colleagues, then me (and forces us out to avoid paying severance), then locks himself out of his account, why should it be my responsibility to help him recover from this situation that he created?
