re: Need some OT advice...

Is there any interaction between you and the owner? If so, I'd tell them exactly what happened. If you say something to your manager first she will cover her own arse with the owner before you can tell your side of the story. This type of shite is exactly why I said I'd never have another job where I was in an office setting. I'm actually dealing with office type bullshite at one of the hospitals that I deal with, so I feel your pain.
