Facebook question?

Hey so I friended someone about 3 months ago and they denied my request and marked me as spam because they were a manager at my job now they’re gone and no longer work there and I can’t friend them how long does it take for the request button to reset


It does not Reset once they Mark it as Spam or that they dont know you it goes away for Good People have a Right to Keep there Work Life Private they dont have to be Friends with people that they have worked with
