That's not really true at all. You just think that because you never hear about it. Stare decisis still applies at a trial level, but its scope is obviously much narrower. Moreover, most things really aren't that novel. Most importantly, its quite hard to research on this level and usually pointless because theres usually a higher level case anyway.

Trust me, other companies are watching this case already and will adjust accordingly.

Of course, they won't stop firing employees who point out inconvenient truths, they'll just be more careful about the reasons they put in writing.
