We introduce a family T consisting of invertible matrices with exactly one nonzero entry in each row and each column. The elements of T are possibly mutually noncommuting, and they need not be normal or self-adjoint. We consider an operator-valued unilateral weighted shift W with a uniformly bounded sequence of weights belonging to T, and we describe its minimal reducing subspaces.
