As others have said, sometimes it's simply not worth it. A person like the PM sounds like they are isn't going to know truth if it hits them in the face. No matter what you say to them, they simply won't get it. Some people lack any degree of recognizable "emotional intelligence." When you encounter such a person, all you can do is make them pay in other legitimate ways. My favorite is to tell the truth about a place on Glassdoor. By doing so I help other job seekers avoid bad employers, and raise the cost of bad employers doing business. It's the purest form of justice.

Personally, I've deeply appreciated a lot of the reviews I've seen of employers on Glassdoor. Just recently, during my last job hunt, I was looking into a couple San Diego companies with promising positions...until I looked them up on Glassdoor. When I saw not one, but many reviews from different reviewers saying such things as "Working for this place will suck your soul dry then crush it" I immediately lost all interest in working for the company. Granted, the Glassdoor reviews aren't perfect, which is why I look for general agreement on the company from different reviewers and/or position titles (as a proxy for different departments of the company).

Sometimes it's worth taking the highroad out so it doesn't cause more dramas down the road.

But sometimes it is funner to burn all bridges.

Burn bridges to light the way forward.

Why would he even do that? Author doesn't want to engage in office politics, he wants to code. Participating in dramatic events is completely counter-productive. Also, consider whose side his co-workers would pick, taking in account whatever happened to the previous two guys.

Well if he didn't want any drama, I'm glad he took the time to write a blog post about it then.

It doesn't have to be dramatic, but I would at least have made it clear that I was leaving rather than being fired. I couldn't stand there silently at a standup whilst some jerk insinuates to my team that I'm being shown the door.

Why would he want to "out" the manager? He already sussed out the situation for himself. He had nothing else to prove to anyone else. He was only there for a short time so probably hadn't made any meaningful friendships with other workers there anyway.

The only thing the OP should have done differently, IMO, is made clear to his colleagues that he handed his notice and that he wasn't being sacked.

I'm pretty sure everyone already knew the PM was an a-hole.

I doubt "outing" the manager would have made the slightest bit of difference.

Better things to out given the security practices Out the company

report to the regional financial services authority. Create anonymous story about how company x is causing massive user vulnerabilities etc.Send this information to the companies clients.You could cause massive damage and come out looking like the good guy if you spun it right.
