United Airlines' machinists union filed a second lawsuit against United CEO Glenn Tilton and two other airline executives, claiming their decision to delay $563 million in pension plan contributions breached their fiduciary duty.
The suit, by the International Association of Machinists and Aerospace Workers, was filed on behalf of four current or former United employees. The suit does not specify an amount sought. Another lawsuit, filed Thursday in federal court in Chicago, also claimed the executives breached their fiduciary duty and violated ERISA and the Internal Revenue Code.
Named along with Mr. Tilton as defendants in both suits were CFO Frederic F. Brace and Executive Vice President Peter D. McDonald. The suit was filed in U.S. District Court in Newark, N.J.
Jean Medina, United spokeswoman, didn't return a call seeking comment.
