tehgerbil:
The two whistleblowers say they alerted senior managers to fake invoices and dubious travel Harrison was taking but were then targeted in a restructuring she helped lead.
I don't know anything more about that case than is in the article you linked to and quoted above:
I suspect that "alerting senior managers" was a mistake, there probably was (or should have been) a policy for making a formal protected disclosure to a person appointed by the board/governing body specifically to handle these issues, who must keep the identity of the whistleblower confidential, investigate, present the findings to the board, and report back to the whistleblower.
It's fraught with problems, especially maintaining confidentiality when you're probably on your own or one of few with access to the information that enabled you to make the disclosure, so you're probably doxxing yourself anyway.
If the investigation hits a dead end, what do you do? You could go to the CE or board, or you could bypass internal processes and go to the SFO. Then you're completely exposed.
Meanwhile, you're faced with working with/for the person you've dobbed in, waiting until something happens...
