It's better to talk it out together.

I feel our Chinese usually would let these kind of things go.  If we choose to forgive & forget others will continue to do that to us.  Sometimes we have to protect ourselves by letting our boss know and even go to the HR.  You don't need to worry too much if you're telling the truth.  I think as long as you do your jobs, who cares what other thinks?  Stand up for yourself is a right way to do.
