I was terminated by a medical device company for falsifying test records on a production line. I did it so I could make my daily quota. I was under pressure and didn't openly discuss this with my supervisor. I've been unemployed for four months now. My performance was otherwise satisfactory. Would it be worth a shot at asking for my old job back, or did I betray their trust in me?
I want you to understand the severity of what you did. Medical devices with falsified test records could be defective and thus kill/injure people. The company has a responsibility make sure their devices don't kill/injure people. I would imagine you also cost them a lot of money, as they would likely have notified the current owners of these devices that they needed to be reinspected so as to avoid criminal charges if the device killed or injured people due to a known falsified record. There is no possible way that you are getting rehired.
You could try, but don't be surprised if you get a hard "No" from them.
You broke their trust in you. That's one of the worst things you could do. If they DO give you a second chance, you have a mountain to climb just to get back to where you were.
Next time, talk to your supervisor about your concerns and accept the repercussions of not meeting your quota.
