For a left type-A monoid S, let τ be the congruence on S generated by script R sign*. There exists a congruence ρ on S which induces the least right cancellative congruence on each of the τ-classes. In this paper we investigate the congruence ρ and give a structure theorem for the class of all left type-A monoids for which ρ ∩ script R sign* is the identity relation.
