I've come to realize that you can do all those things and make a simple mistake that results in you losing your job. I think this usually happens when that simple mistake has caused a major loss for the company. It's as if all your hard work means nothing when you mess up.. I've realized the further up the ladder you go, the more likely you are to fall. Leaders for companies have a lot of accountability and when someone makes a mistake, they are responsible and are often let go for allowing other people to make mistakes.
You can also contribute the most profit to a company and they let you go for something that is only speculation. I know someone that was selling the most in the entire district and worked for the company for three years for them to suspend her for something that was speculation. The employee then informed me that they were successfully able to clear up her situation but decided not to give her the position back.
The other part of it is that you don't know what the future holds for the company you work for. Some companies don't tell their employees that they are closing until the day it happens. I've also worked for a company that was essentially training us to lose our job. (yes, that's what I said) The company wanted us to show customers how to do things themselves and there was an incentive for doing so.
Not everyone is destined to be an entrepreneur but everyone can use their money wisely so they can live life instead of simply survive.. If you find that you are meant to work for a company then I highly recommend investing so that your money grows in a way that you don't need your job. You should work because you want to, not because you have to.
