Advice needed......

[snickerharley]

Some of you may of read one of my previous post about a co-worker with imprper hygene, and a nasty/rude disposition to her co-workers and customers. Well recently this person has started to get rough with customers beloved dogs, and this person seems to have no feelings about the disgusting manner in which this person treats the dogs. I have complained and filed papework, but there is not much we can do without physical proof.

So on to my question because this has been driving me mad, I'm at home getting upset about it and it is constatntly on my mind. Should I just ignore it, to save my sanity , because nothing is getting done about it at work. Or should I keep making complaints possibly putting my own job at risk?

Thanks in advance for any advice
