> I believe many US states have similar procedures.
Most US companies follow similar procedures because they are a sensible thing to do. But 49 out of 50 US states have "at will" employment which means that employers can fire any employee at any time for no reason at all.
"At will" employment, especially for larger organizations, does not mean this. There are lots and lots of cases of employees, in nearly every state, suing for wrongful termination and winning.
