Changes to retiree health insurance - Tribune Publishing

I've been told that if you are a pre-65 retiree, you must make a new election for health benefits. Here is the info I was sent:

"Tribune Publishing is changing some of the retiree health insurance companies for pre-65 retiree coverage. The PPO coverage in CA, for example, is going from UnitedHealthcare to Blue Cross/Blue Shield of Illinois. If you want to continue your retiree health insurance you must make a new coverage election. If you don't make an election you will loseyour retiree health care coverage and not be able to re-enroll. The enrollment period begins today (Nov 17) and runs through December 1.

"The enrollment website is:www.mercermarketplace.com/tribunepublishing

The new phone number for the TribPub benefits center is (855) 543-4117."
