This is objectively untrue. Yes, there is at-will employment which is pretty commonplace, but there are many reasons you can’t fire someone such as discrimination, retaliation, or workers’ compensation. If you’re in a union or a contract worker there may be further termination procedures in place.
That isn’t to say state/federal labor laws aren’t utter shit, but the statement about firing for any reason needs a big asterisk next to it.
