I know of a number of ex AT&T employees going after the company for age discrimination. In its layoffs, the company clearly targeted older employees and kept younger ones. I also know of instances where laid off workers trained their much younger replacements.
Given Stankey’s call for a younger workforce, and recent settlements of age discrimination claims for added severance, anyone who is older who was fired by AT&T and thinks it may be age related should consult a lawyer. Don’t take it passively.
