I'm not the poster you were responding to, but I have some experience in this. I am an engineering manager at medium size US company. If I want to fire a poor performer it requires a couple months of detailed documentation on their poor performance, and that's just so I can get them on a PIP (performance improvement plan). That's another 30-90 days. The PIP takes time to prepare and performance during the PIP also has to be rigorously documented.
This has been my experience at two different companies in multiple cases with egregious underperformance. I suppose if an employee assaulted/harassed someone or was doing something else outright illegal like theft or embezzlement, they would be shown the door immediately. But if someone is half-assing their work and dragging the team down, everyone has to put up with it for months as they get second chances, micromanagement, and other special attention before they can actually be let go.
I think it's due to the litigiousness of the US culture. Yes, US companies can fire people at will, but they can also file lawsuits at will, which are costly (time+money) no matter the outcome.
