tl;dr: Subject to layoff dread at a moment's notice. Late stage capitalism is fucked up.
Every time I've been laid off, the ax has fallen in the same way: an unexpected meeting invitation from a manager, with a title that only names (some or all of) the participants and no specified agenda.
A month ago, 3.5% of my department was laid off.
Two days ago, I got a meeting invitation for today from my manager “Bob” titled “Rahul : Bob” – no agenda included. My heart stopped. After spiritually collecting myself as best I could, I summoned the courage to reply asking if I needed to prepare in any way. He answered that he just wanted to catch up. I didn't think he's the kind of soulless corporate monster who would lie about that – but you never know until you know.
Got out of that meeting a little while ago; I was not laid off. But what kind of meatgrinder system leaves people susceptible to such terror?
In conclusion: Eat the rich.
