IBM guilty of discrimination in pensions case
E-mails from benefits consultants Watson Wyatt to top human-resources executives at IBM in 1999 give a detailed look at how some of the company's pension changes would affect younger versus older workers and perhaps cause thousands of employees to stop building a new benefit for several years. The memos were exhibits in the court case, in which a federal judge in Illinois ruled that IBM had discriminated against older workers when it changed to a cash-balance pension plan in 1999. Older employees sued IBM, saying that the new plan provided them with less favorable benefits and caused some of them to cease building a new pension benefit for a period of time. IBM intends to appeal.
