Actually, I said that the stated disadvantages were not likely to be real.
Where the split may be very good is if it facilitates greater cooperation among the Change to Win folks and, hopefully, among the remaining AFL unions. Cooperation that alluded the large mass of unions may be possible in smaller groupings.
Which is borne out by this announcement yesterday: http://tinyurl.com/dnkqg
"Five unions in the Change To Win Coalition announced today they are backing low-paid janitors in Houston and Indianapolis who are uniting to win good jobs with health care by forming a union with SEIU (Service Employees International Union). The janitors, many of whom make as little as $5.25 an hour, work for ABM Industries, the nation's largest cleaning company.
At a rally Thursday night in Chicago, Brian Rainville of Teamsters Joint Council 25 announced that if the janitors reestablished picket lines in Chicago, that Teamsters Joint Council 25 would sanction those strike lines for its more than 100,000 members. Teamsters Joint Council 25 members include garbage pick-up, delivery, garage and parking workers."
