The United Auto Workers and the Detroit automakers have been locked in negotiations for months now, as both sides seek to redefine their relationship in the post-bailout era. And though all sides have stressed the importance of avoiding intractable disputes in an alleged new spirit of cooperation, it seems that the prospects of a quick, painless conclusion to negotiations remains elusive. The UAW’s contracts with Chrysler and GM both blew past their deadlines at midnight last night, and Ford, the only manufacturer at theoretical risk of a strike, extended negotiations earlier this week. TTAC has not covered these negotiations in much depth for the simple reason that little information leaks out of them. But with contracts expiring and optimistic rhetoric crashing on the rocks of reality, the frustration is clearly starting to boil over. And who is surprised that Fiat-Chrysler CEO Sergio Marchionne is the first to let his frustration show?
