Way to generalize...good job.
Perhaps you did indeed 'change things' but the reality is that's not the norm. I could have bitched and complained and written letters...you name it...but nothing would change, nothing. And in the world of megan corporations, one person is rarely going to say something (especially walking out the door) to bring about change.
as they say, When you have them by the ba!!$, their hearts and minds will follow" You and your associates had them where it counts. That is seldom the case, even though most of us think we do.
IMO, the OP has a tough job. Being swallowed up by a bigger company, mergered with equals (never the case inspite of the PR) etc is a difficult thing to endure for the long term. The whole dynamics of the "new" company changes. To endure, one must have the attitude of the OP's manager. She seems to have made the necessary corporate-rewarded changes. I would not have, oh wait, I didn't
As mentioned by others, there is no benefit at all to spewing your opinion to either the boss or their boss. Just quietly submit you resignation and be the "better person".
