A total of 670 J-C Penney employees will lose their jobs this summer when the retailer closes its distribution and call centers in Wauwatosa.  The Texas-based company confirmed its plans to make that move Tuesday, moving the distribution to facilities in Kansas and Ohio by July.  It says its supply chain network is oversized when compared to its national store footprint.  The customer care activities are moving to Lenexa, Kansas — closing operations in Wauwatosa by September.
