For a UK contract (and probably USA), there is a clause that says 'if any party decides to end the contract, so be it, and there will be X weeks/months of notice". I don't know what anyone's contract says, but the law in the USA is clear. Notice (and cause) are strictly optional. People offer two weeks notice when leaving by convention, but it is not required nor rewarded. You can be asked to leave at any time with no warning nor compensation nor explanation.
