What could the wage data show you? That everyone in all these companies were being paid much the same for similar positions? Doesn't seem like that would prove much of anything. You would have to somehow compare data from these companies with companies outside the group. But even then, I'm willing to bet it would show little because these companies were the big guns in the area. Very few companies would be able to outbid them in wages in the first place. Wage data is probably not really needed here. From what I understand of the law, the mere fact that they had the agreement was illegal. Meaning they didn't even have to implement the agreement, just that they made it. That they seemed to have implemented it and attempted to hide it only adds to their problems.
