Hi,
I agree, what the person did is completely wrong and a violation of privacy and trust.
I would address this person personally and let them know that you are very uncomfortable with them looking at your financial history and let them know you know how serious this offense is!! That way they know (even though I'm sure they already to know) that they stepped over the line and could lose their job.
But then I personally would switch banks and leave it at that. I know its against what everyone else thinks and I know she did something very wrong. But I just wouldn't have the heart to end her career. I know its not my fault and I am not ending her career, her actions did. But its the holidays and I believe in second chances. Think of her family. You tell, she gets fired, and can't get hired anywhere else. I just couldn't do it.
Now if she stole money or something I would feel differently. But just my opinion, I couldn't do it. I couldn't end her job and career. Again, I know I didn't do it, She did by her actions. But I would talk to her personally and give her a second chance to think about what she did. And then I personally would switch banks.
Please don't slam me with lots of mean posts, I know its only my opinion and I respect others opinions as well.
Just follow your own heart and do what you feel is best.
Happy Holidays!
Shelly
