4 months is not much of an incentive. Retirement eligible employees who believe they are safe will stay and those who believe they are vulnerable will wait to see if they get selected for the involuntary phase that has a much larger payout. Predict voluntary phase will be woefully undersubscribed and this will end up being mostly an involuntary program.
Also, love the nebulous criteria laid out for selection in the involuntary phase, including “long term fit with ExxonMobil core values?” This really means there are no objective criteria. Of course, we could take days talking about what those core values REALLY are.
