This engineer in my team told everyone he's on Focus

There's an SDE on our team who recently told everyone he's on Focus. He tagged the manager, the SDE3, and another SDE, complaining that they weren't responding to his emails. He set up a design review and asked everyone to join, mentioning it was his last task on Focus. His design document had some sarcasm, which makes sense since I've seen him get targeted and cornered in past reviews. During the review, he got into a big argument with the SDE3, who told him to "be civil" and "not play the blame game." It’s sad because he’s a friendly and smart guy and from one of the top colleges in my country. There is a rumour that some of the team mates wrote a one pager document and presented to the manager on why he's no fit to be at his level. Bunch of 🐍🐍 honestly. The team culture has really gone downhill, with many people choosing to leave. I’m planning to leave soon too. I'm not sure why he told everyone he was on Focus—it seemed like he shot himself in the foot. What's worse is he came to Amazon from a faangmula+ company which is known for having much better WLB, just for a higher level. When I joined, the team culture wasn’t this bad, but things have changed a lot. I’m just glad to be leaving soon. Anyway, rant over.
