Do you speak up when you feel taken advantage of or abused?

I usually dont speak up. I am afraid that someone will be combative with me if i do. Then they will attack me by trying to start an argument.

I really should stand up for myself. This one place I used to work at, a fellow colleague was so mean to me in front of the whole department and no one even stood up for me. I should have stood up for myself but no one else that was a senior within earshot stood up for me either. With the harrassment I recieved there, I should have filed a lawsuit. I was encouraged to by others in the company but I didnt do it. Needless to say, I dont work there anymore.
