Most companies are internally run like communist dictatorships. Leadership is only marginally interested in the conditions of their underlings but they compensate for that with spreading a ton of propaganda. They send out mission statements ("We believe in..."), company newsletters, hold motivational meetings. But it's almost always a one-way street. Lots of information comes from top down, but almost nothing trickles up.

In the end you just have to accept that below a certain level you are not part of the "in" group and the "in" group has no interest in your opinion. They are only interested in what benefits them.
