That's a rather naive view of the work environment. There's a myriad of reasons why it is hierarchical of which not the smallest one is so people down who have a limited field of vision and expertise do not jump into decision making above their pay grade. Doing it once may be acceptable but the issue of course is that one is unlikely to know when is the time do that stick the neck out. Doing it multiple times pretty much guarantees that one would find out that he or she is imminently replaceable.
