AFL-CIO president John Sweeney knows the UPS strike isn't about packages or pension funds. It's about making Big Labor, well, big again. So Sweeney is prepared to put up $10 million a week for "many many weeks" to bolster the Teamsters' resolve. "Because their fight is our fight, we're making this strike our strike," Sweeney said late Tuesday, after spending the day shoring up support from union presidents. The loan ensures mainly that striking workers get the $55 a week in strike benefits due them starting Thursday. UPS, meanwhile, says the strike is costing it $200 million to $300 million a week, and continues to appeal to a stone-faced Clinton administration for intervention. Well, if the Teamsters can turn to their union pals, perhaps UPS should call FedEx.
