Retiree Open Enrollment

ATC Management Inc. believes in taking care of its employees and their families, whether they are actively working or in retirement. In an effort to maintain one of the key components of our retirement package, the ATC Retiree Healthcare Plan, we are making a few changes as outlined below. These changes will take effect Jan. 1, 2022.

These changes will take effect Jan. 1, 2022. All forms should be returned to Sara Wilder via email or postal: P.O. Box 47, Waukesha, WI 53187.

If you choose not to enroll in ATC’s Retiree Healthcare Plan during this open enrollment period, or if you drop your coverage at any time in the future, this benefit will no longer be available.
