I'm not sure if I exactly understand your question, but certainly our research has demonstrated that the wage gap tends to be greater in non-unionized places of employment, that it tends to be greater for part-time employees, and that it tends to be greater at the lower levels of jobs.
I think part of that has to do with—and we sensed it, although we really weren't in a position to do very much investigation—the fact that there are a lot of situations where you have double discrimination, if you like. Where you have racial factors or disabilities or aboriginal workers, that seems to compound the wage gap although, as I said, we weren't really able to investigate that.
