how do i get a hold of the people at the top of the McDonalds employment chain?

Hello,

Its all about research. Go to their national website and look up the profiles and you will see who is who. It would be great of create a LinkedIn account so they can view your credentials before they respond back to your inquisition. https://www.mcdonalds.com/us/en-us/careers/meet-our-people.html. Let the journey you are on be a prosperous one.

If you still employed there. Work diligently, lead by good example and be prepared to seize opportunities for leadership & training.

Try searching on LinkedIn. You'll wanna have your own account.
