I will tell my story: I found a huge accounting error that allowed for several employees to embezzle funds. I disclosed it to the main stakeholders and some people went to jail. The accounting team still refused to acknowledge that the mistake was theirs, so I left on principle.
A few weeks later, I was talking to an old colleague and they revealed that the story that came from stakeholders was that the accounting team found the error, and I left in disgrace (despite that not being my department?).
So if you find an embarrassing mistake and you do not control the narrative, you have to proceed very carefully.
Had one like that. I quit and they blamed me for a project failure after the fact. That pissed off a couple of colleagues who thought it might happen to them. They also quit leaving them entirely without a software team. Set them back ten years because they didn’t make the market in time.
Write everything down and make sure everyone knows you’re writing it down. Saves a lot of hassle like that.
I don't have the full letter at hand, but basically:
- new job paid almost 3x than this one
- I was the sole maintainer of an important project and they had no one else
so they made me not tell anyone I was leaving, and the letter was edited to make it less obvious how much of a better opportunity the new job was.
