Violence at the Workplace

"Have you ever been slapped, kicked, shoved, or bitten by a patient? Have you had your hair, earring, or clothing pulled? Has a patient ever thrown something at you, knocked something out of your hands, or spit in your face? Has a relative used abusive language, sworn at you, or threatened you if you tried to enforce a hospital policy or did not comply with a demand?
If the answer to all of these questions is "no," consider yourself one of the lucky few nurses to have escaped verbal and physical abuse at the hands of patients, family members, or visitors in the course of your duties."

I know the article was discussing violence in the healthcare environment, but I also know that violence occurs in many other workplace environments.

Have you ever been assaulted at work?

Have you witnessed someone else been assaulted on the job?

Does your supervisor/employer have the right to verbally or physically abuse you?

Have you assaulted someone at work?

 Is there ever any justification for it?

Someone said to me, "Sometimes these employees are so dense, you need to yell at them to keep them moving."

I don't agree.  Do you?
