I have seen that article and I disagree with an important theme of his re the proliferation of rj flying through relaxed scope:

"....This did not result from some stingy, scrooge-like effort by management; it was standard operating labour procedures that used scope liberalisation as currency to wrest gains for mainline pilots, which ultimately came at the expense of their regional counterparts. With friends like that..…as the saying goes...."

The framework for the explosion of regional flying was already in place when the RJ came along, scope has been relaxed most recently to protect on the downside rather than to "wrest gains", and its hard to make the case that relaxing scope has come at the "expense" of regionals.

All that being said, I agree with him that negotiations in the immediate future will be enormously important, and I have the feeling that for mainline pilots, protecting scope will be of the utmost importance to take priority over all else.
