I told the CISO he was an idiot who didn't understand security (in front of many peers), because we disagreed on implementation. Soon after I was fired for "violating company policy".

I realized being right is not the most important thing in the world, certainly not more important than being employed. The other lesson was to never involve myself in office politics again: it is irrelevant and ultimately lowers your standing in an organization.

Another lesson you missed: don't be disrespectful to coworkers, including bosses. You are not entitled to offending people in a work environment.

Just because he/she didn't explicitly type it doesn't mean they missed the lesson.

Thats a lesson that you have to learn at work?

How does one get away in life being disprespetful to ppl you interact with. I don't get it.

Yea I think the real lesson here is 1. treat people with respect even when you vehemently disagree and 2. You were really bad at office politics. The entire name of the game in politics is to piss off the least number of people possible.

So you were fired, not laid off. If you're a wagie (even making 500k) i would just smile and collect the paychecks.
