Some possible words include "unkind," "malevolent," "nasty," "venomous," "petty," "spiteful," "cruel," "vindictive," "hateful," "envious," "jealous," "resentful," and "mean-spirited." These words accurately convey the negative attitudes and behaviors of someone who may exhibit bad-mindedness towards others. Choosing these alternative words can help to maintain a respectful and professional tone while still expressing disapproval of negative behavior.
