open and supportive and not accusing
In the following quote from article36 from the main page:
They say: "You want to be seen as supportive and open, rather than accusing.".
But how to do that? What do you say or do to seem supportive and open, and not accusing?
"Be supportive and open" means to approach the co-worker like you would a friend or relative. I would say something to the effect that I'd like to have a small talk when he/she is available. During that talk, I would try to get some information that would help me understand what the person's problem might be. (Is he/she bothered by someone/something in the work environment? Are they feeling well?)
"rather than accusing" means that you don't want to say something like, "Gosh, Bob, you're a real jacka$$. Why don't you just quit it?"
It is said that the best way to go about voicing one's feelings in regard to another person's actions is to avoid starting sentences with, "You always . . ." because that makes the other person defensive. The best way is to express yourself by saying, "I feel ____ when you ____." I would then ask that person how the two of you can work together to correct the situation.
