That is simply not true in the US. By default, in all but one US State, employees can be fired with no notice for no reason (or for any reason other than a handful of specific exceptions like "because of your race"). The legal departments of most companies feel that having a clearly specified contract would weaken this right, so as a matter of policy they do not have contracts with the majority of employees (this includes most tech employees). They have employees sign separate contracts for things like "keeping all the company's secrets", "granting ownership of copyrights and patents" or "promising not to work for any competitor for some length of time", and these contracts are not tied to their salaries. You are welcome to decide that you don't like this system, but you will find it difficult to find employment.
