Why you should consider being a jerk What you can learn from the jerks at work

Having an opinion and taking credit for your own (not other people's) ideas can make you stand out at work. Being assertive and speaking out when you have something to say can make you look like a leader.

Just remember there is a fine line between being assertive and being pushy, and the aggressive loudmouth on the team who nobody likes generally doesn't last too long. So learn from the jerks, but don't become one.
