If you worked at a McDonald's, you get paid an hourly rate. $8 an hour. Think about how many hamburgers you make, how many get sold because you showed... up to work. The reason your pay is based on your time and not output because at $7 a hamburger, that's like $1000s of dollars mcd would have to pay. That's the difference between your pay and your output. All companies do this and it's safe to say yours is too. Workers are having their value stolen virtually everywhere. That's the mentality you need to have to know that the company is not your friend. It is a contract and you are always going to get the raw end of the deal. So if the company doesn't want to fire you over a mishap then you DEFINITELY don't have to care because they COULD very well pay you a livable wage but they won't so don't sweat it.  more

Mistakes are a part of life, work, and growth. The key is to learn from it and use it as a tool for improvement. I absolutely love that you care... enough about your work that it has an impact on you, but as your boss said it's time to move on. Otherwise it's likely to cause you to make more mistakes because you're obsessing over a past one. Stay there, and reward your supervisors faith in you! more
