Every manager I had at every major multinational company only had the interest of their own career progression in mind, not the company's, not their team's. You as an employee under them were just a means to their goal, nothing more. I naively assumed that making them look good and doing the overtime when needed to achieve their idiotic deadlines would also guarantee my ascension later, but boy was I gullible and wrong.
Going the extra mile for your boss might work out for you when everything goes smooth in the org in times of economic prosperity when there's room for everyone to move up, but when the org or economy went tits up, and things were being put on chopping block, those managers didn't hesitate to grab the only parachute for themselves and let their team sink or throw them under the bus to save themselves at the tune of "So Long and Thanks for all the Fish", so I learned the valuable lesson to not go the extra mile for any boss unless I have written guarantees of a reward.
It's the way the reward system is set up in these companies. Climb the ladder and kick it under you after you dangle the carrot in front of naive idiots to push you up that ladder for rewards they might never see. I think someone called it "the GE way".
