Pros
-Big company with decent benefits. -Multiple refineries (seven) in various locations in the US so there are opportunities to move if desired. -Pay is direct deposited on time. -Working for Marathon is better than being unemployed.
Cons
Process engineers have been leaving in droves. Probably the singular most important employee type in a refinery and Marathon can't keep theirs and that is not a good sign. Company equates legality with ethicality. Employees that are no longer wanted/needed are marginalized and treated very shabbily with the hope that the worker will move on. MPC has a 1950's mindset (see corporate HQ in Findlay, OH) and expects 60+ hour weeks for significantly less pay than other refiners in Texas. MPC does all the typical self congratulatory stuff regarding safety, ethics etc. but the rank and file see something quite contrary. Management like to "shoot the messenger" although they bang the drum quite vigorously about "doing the right thing" and speaking up etc.
