The y-value is just used when individuals are hired into the university, so it's not helpful in addressing that particular issue. We do have something called the anomalies fund. As faculty members progress through their careers, we do an analysis of faculty salaries—again, faculty by faculty. We create a regression line, and individuals who are below the regression line can submit to the anomalies fund for an adjustment. It's not a perfect mechanism to address the trends and issues you're speaking to, but it is one we do have embedded in our collective agreement.
There are measures along the way where faculty can put their hands up for salary adjustments if they are anomalously low.
