Can you still get in trouble if you admit poor workmanship long after a company went bankrupt?

I think it would depend on whether someone who was affected by your lies and poor workmanship had grounds and desire to file suit and hold you responsible for any damages.

I don’t know about the legal aspects, but at one of my jobs, my boss recalled a story about how he got a job as a commercial paint foreman. He knew absolutely nothing about paint, and told us how he bullsh* his way through it. Made me lose respect for him.

It’s not illegal to not do a job well because you aren’t any good at it. You did your best to line those rivets up, but the workmanship was shoddy. Your products would suck as a result, and people would not buy them or return for a refund, so the company goes bankrupt.

But lying is a different beast altogether. Because you put the rivets on the wing but weren’t good at it, and then signed that it met a standard such as an FAA airworthiness certificate, you ‘d get in trouble for lying when the wings fell off and the plane crashed. Or saying you did three welds when you only did two, and the pipeline broke. The lying gets you in big trouble even years later.

Unless you libel some of the people you worked with, I don’t see what issue there would be.
What are they going to do, fire you?

Do you still know any of the people you worked with there?
What are the chances that they are going to read what you are writing?

You worked for a company and they kept you on despite some of the things you didn’t do well. That is on them. You were an employee, not on the board of directors. You have sort of a protective umbrella. If you slander someone else in the company in the process they might have reason to deal with you for that, office politics and all.
