Manufacturing Shift Manager - Bolton, ON

A mutually rewarding experience.

Work. Realize your ambitions. And realize there’s more to being in business than just making a profit. That’s the Mars philosophy. And the opportunity we offer every one of our Associates. An opportunity to take what you do and make it mean more for you, for those around you and for the planet.  What you get here is challenging, interesting work. You get the tools you need to do a great job and you get to have the best possible people on your side to help you do it. And at the same time as getting to find ways to do business better today than we did it yesterday and driving a great career, you also get to build a more enlightened business and drive sustainability.

Because it’s never just about a single person, a single project or a single brand. It’s about how you can grab everything that’s within your reach here and use it to pursue mutual, long-term gain. It’s about having ideas. And ideals. Being prepared to risk failure because the promise of success means we’ll all be a little better off. It’s that mix of integrity and ambition that makes Mars such a special place to work. And why working here is always about more than just a job.
