Marathon Petroleum - Layoff rumors, anyone have concrete info?

Okay, trying to get a pulse on what's actually happening at Marathon Petroleum. I've been hearing increasing chatter about potential layoffs, particularly in certain mid-office functions and possibly some operations support roles. No official announcements, obviously, but the rumor mill is churning pretty hard. People are talking about 'right-sizing' and 'efficiency drives.' I've been checking internal comms and talking to folks discreetly, but it's all hearsay and speculation so far. Some are saying it's just a standard cyclical adjustment, others are predicting something more significant. If anyone has heard anything more concrete, or even specific departments that might be affected, please share. Trying to get a clear picture before the holiday season really kicks in. Any intel, no matter how small, would be appreciated. Just want to be prepared.
