Only 18 states, including Massachusetts, have specific provisions that allow women who quit their jobs due to domestic violence to qualify for UI.
More states lack rules for allowing UI for women quitting under domestic violence reasons than those states that do.
Since the context says only 18 states have these provisions, there are still many more states aside from those that do not.
