In practice, at any larger corporation with an HR department, despite the law saying so, you can absolutely not fire anyone for any reason. As a manager you’ll have to go through a 1+ month process of documented coaching, performance improvement plan, etc to gather evidence in case the employee sues after being let go. So not sure if Steve is technically correct here, but he is very much practically correct. It’s been like this in big tech, which is what Steve is talking about, for a long time.
