The PA system, even if sucky, like any of the Exxon systems will take a lot of time (and word from the top) to change again. In the meanwhile, just buckle up the seatbelt and go along for the ride. If you feel like puking or if you don’t have pressure of monthly bills, you should leave the place. Otherwise, it’s not good for your health.
But you should know one thing Exxon managers are very very very very bad at - and that is telling the emperor / empress that they have no clothes. Instead, the managers will just fawn over their top bosses and telling them how nice their new clothes are, even though they may be stark na--d and unshaven.
All the best
