Former Teamsters Local 604 Principal Officer John Thyer dies


John G. Thyer Sr., who recently retired as principal officer of Teamsters Local 604, passed away Sept. 6 at his Bunker Hill, IL, home after a long battle with ALS, a neurological disease that involves the nerve cells responsible for controlling voluntary muscle movement.

Brother Thyer, 64, became a member of Local 604 in March 1978 as a driver employed by Complete Auto Transit. While employed at Complete, he served as committeeman and was elected as shop steward in April 1988.

He was appointed as an officer for Local 604 in July 1989 as a trustee and served in that position until he was elected as principal officer January 1994. He had served in that capacity until his illness forced him to retire on March 31.

Brother Thyer also had served on the Teamsters Joint Council 13 Executive Board from 1996 to 2001 as trustee and recording secretary.

“I have known John for over 20 years, since when he became principal officer of Local 604,” said Marvin Kropp, president of Joint Council 13. “I’m sure John will be greatly missed by his members at Local 604 in which he took a great interest in representing them to the fullest. The Teamsters Joint Council 13 Executive Board expresses its condolences to the entire Thyer family.”

Brother Thyer is survived by his mother, Charlotte Thyer; his wife, Cindy Thyer; his eight children, Jodi (Joe) Potthast, Richard (Emily) Thyer, Katie (John) Mirkovic, Amanda (Steve) Moore, Angie (J.R.) Santel, Julie (Shaun) Watson, John (Allie) Thyer, Jr. and Nick (Jessica) Thyer; and several grandchildren and great grandchildren.
