It took me awhile to answer this post because i don't want to come off insulting but,
actually DA, your supervisor is right. how did your supervisor find out about it?

I would just worry about my own work and leave other co-workers mistakes for the supervisors to deal with. i wouldn't say a thing because it really wouldn't be my place to do so.

You really do have to be careful with things like this in the workplace.
