AbstractA notion of reducibility in finite posets is studied. Deletable elements in upper semimodular posets are characterized. Though it is known that the class of upper semimodular lattices is reducible, we construct an example of an upper semimodular poset that is not reducible. Reducibility of pseudocomplemented posets is studied
