" I never deserved my harassment. My boss constantly admitted I did a good job and gave me good reviews. But still harassed me and demanded I do demeaning things.."

there must be some reason the company still has her employed after all those years. if indeed it was so terrible, with the economy today I would have thought they would have let her go ...so she must be doing something right. frequently as a manager you see things in a different light then as an employee. there is a totally different view ..your friend has some value to the company or she would be gone .

honestly I would be wary of your "i'll just do a worse job going forward" attitude....she got reassigned, you might not be as lucky...you don't know the details of management's decision...the why's of what they did......be careful. they had a place for her, you might not be so lucky.
