I hate to break it to you, but I'm your boss. Your complaining and dissatisfaction fall on deaf ears, most of the time. You can be replaced. Keep it up, and you probably will be. Don't shoot me, I'm just the messenger.

No matter how useful or clever you are, or how hard you work, your continued employment is an economic decision: you earn your pay (and more), or you don't. If you don't, you're probably headed for the unemployment office at the next downsizing opportunity.
