Pros
MPC use to be a great place to work int they merged with Andeavor. Great people who were passionate about their jobs and doing the right thing.
Cons
Since the merger, many people have left or been pushed out for speaking up on life safety issues or doing the right thing. Policies are changed when management wants a change, not from a top-down direction but more of " the fix watching the gen house". This causes lots of problems when people are more focused on cutting costs and making bonus while having an attitude of that will never happen. They have recently been routinely putting people on performance reviews to create a false paper trail in order to fire them. Most of these people have previously always received great reviews and the maximum bonus. No longer the great company it was.
