The kindness requirement is awesome and refreshing. I was shocked just how much vitriol gets spewed in an average workplace, directed at customers, fellow employees, inanimate objects. I gravitate towards the people I work with that aren't like that, so specifying 'kindness' right up front is great.
I wish more job descriptions were like this one. Straight and to the point, not much fluff or buzzword padding all over the place.
