United Auto WorkersAutomotive News is reporting that Chrysler and the United Auto Workers have extended contract negotiations for an additional four weeks. The talks are bent toward a new wage and benefit pack that will impact around 23,000 workers. Previously, Chrysler and the UAW were operating under a one-week extension that expired on Wednesday, September 21, and the new extension allows the union to focus its effort on talks with Ford.

Automotive News reports that those negotiations may be a bit more complicated than those with General Motors and Chrysler for several reasons.

To begin with, the UAW expects Ford to give back many of the concessions that union workers made in 2007 and 2009 as Ford tightened its belts during the economic slump. Those concessions included a wage freeze and a stop on any cost of living increases. Ford, meanwhile, wants to increase profit sharing and bolster its bonus structure in place of increasing its fixed labor costs.
