|Some companies operate like a corporate version of an emergency room because of the nature of their industry, while others do so because it is the nature of the business or its owners and managers. Regardless of the cause, it is very difficult for an employee to have much of an impact on this mode of operation.
The fact is that you have been there for two-and-one-half years and you find the work to be fun. That is more than many people can say about their work, even in crisis-free companies. There may be something about this fast-paced, unpredictable, and exciting environment that is particularly satisfying to you.
As for the manager who is being overlooked, this is an issue for him or her to handle. This person may think that the job is just as much fun as you do.
The company owner's behavior is typical of many successful entrepreneurs -- rapid decisions, operating on "gut feel," and ignoring the chain of command. He has advised you to get used to this, and it sounds like you have done so.
