Not every best guess, decision, or practice is good enough to secure profits for an upstanding and well known firm. There are massive entities that have failed due to mistakes and, more often, bad decisions stemming from criminal activity in some form or another. Corporate greed does little for the company's reputation. It only reinforces the fact of corruption in the business world. This is seen best by the reality of deception and thievery in its many forms.
There will be times in the life of an organization that will give rise to the rock and a hard place existence. It's during these and other times conferring poorer coping opportunities that bad decisions are made. Bad decisions are defined as those leading to criminal acts as well as loss of profit. Executives need some form of oversight to occur so that crimes are known and prosecuted.
To build a company it clearly requires time and excessive knowledge, but where the money falls short some leaders are given to bad behavior. This is how a corporation fails. With inappropriate behavior, the firm loses its reputation and, in many cases, it can't recover. With a lack of a good reputation investors walk away as do productive workers because permanence is no longer assured. The failure lies in the choice of leadership and their errant actions.
Working for a massive company is no guarantee of mobility or better pay. It's possible to make great strides in business at any firm, size not an issue. But based on the example of the corporate world, it just seems like a better idea to establish good working relationships at every firm that employs you. To a part of the memory of a firm is an added advantage to getting future employment and pay raises. So, since there is nothing written in stone promising exactly what you're looking to achieve due to the poor leadership of corporate executives, maybe it's time to pursue other interests and form a corporation of your own.
