dcblogs writes: An angry letter from Sen. Dick Durbin (D-Ill.) protesting Abbott Labs' IT employee layoff may be having an impact, but not the way the senator wanted. The layoffs are part of plan by Abbott to shift some IT work to India-based Wipro, a major user H-1B visas, and Abbott is proceeding with the cuts despite Durbin's plea "to reconsider this plan and retain these U.S. workers." Abbott put the number of impacted IT employees at "fewer than 150." Durbin's letter has it at 180. But Abbott may be making changes in how the layoffs are conducted. IT employees, who only spoke on the condition of anonymity, said they were initially told they would be training replacements. But Abbott said Friday that the "affected Abbott IT employees are not being asked to train their replacements." The firm's statement appears to confirm the latest employee accounts of what's going on. One worker said the replacement training may be limited to employees who aren't losing their jobs. The training of replacements was a major issue for Durbin. In his letter to the firm, Durbin wrote: "To add insult to injury, the Abbott Labs IT staff who will be laid off will first be forced to train their replacements."
