In my role as director in Ontario, we receive calls daily, especially from women trying to improve their working conditions by wanting to join a union. A lot of those women are in precarious work but are working two or three jobs because minimum wage just isn't cutting it. An increase to minimum wage would help with the fact that they wouldn't have to work two or three jobs. They would be more available, not only to society but to their families as well.
I also agree with the comments that Meg has made.
