Made a mistake in previous job. Looking for work at animal refuge centre where old boss works.?

Question

I used to work at a science centre. I had had no previous experience in working with wild animals. I was nervous to start but very passionate about doing well.
Unfortunately, one morning when I was misting some of the habitats and cleaning the water dishes, a small amount of bleach water had been left on the counter where I had placed one of the bowls. The following morning, one of the tree frogs had died. I understand that the gravity of one, tiny tree frog dying may not seem very bad to most of you, but where my job was concerned, I probably appeared to be unprofessional, maybe even "immature". The fact of the matter is that I took it upon myself to complete the morning tasks before everyone arrived and simply made a mistake. I was then transferred elsewhere to finish my credit.
I'm now looking to volunteer at an animal refuge centre where she also works. How should I approach this situation? What if she recognizes me and makes me look bad to everyone else? What if she mentions it?

Answer 1

It seems like a perfect opportunity for you to prove to her that you have indeed changed, and matured into a responsible individual. Most people don't get a second chance like this - I think you should go for it and show her what you're made of. Good luck!

Answer 2

Her knowing your history might be a good thing. You obviously felt bad about it, and you are older now. It's clear you learned from the experience. Go get that job.

Answer 3

She will look bad if she says anything. You are older and wiser now. If you see her say hello, don't hide, you didn't do anything shameful like stealing.
