If you believe this, it&#x27;s not safe to fire <i>anyone</i> --- all of them could &quot;file costly wrongful termination suits&quot;.<p>In fact, &quot;wrongful termination&quot; doesn&#x27;t mean &quot;terminated unfairly&quot;. It means &quot;terminated <i>unlawfully</i>&quot;.<p>In the US, unlawful termination occurs:<p>* When it contravenes an explicit clause in your employment contract or an implied contract you accidentally created.<p>* When it has the effect of discriminating against a protected class.<p>* When it violates the ADA.<p>Employers in the US generally have no obligation whatsoever to provide &quot;reasonable time to take corrective measures&quot;. Things like PIPs have two purposes:<p>* As an attempt to bulletproof firings that target ostensible members of a protected class<p>* As a humane &#x2F; bloodless way of notifying employees that they&#x27;re about to be fired and should start looking for a new job.
