You are the HR manager of a technology firm that has grown significantly in recent months. One recent hire was the breakthrough $$ a bio$-$engineer who seems to have a creative genius for manipulating living organisms to enable them to clean up toxins. But a chemist in his department has been harassing the bio$-$engineer, you suspect because of the bio$-$engineer$$s sexual orientation. The chemist is a big fellow who has previously made disparaging remarks about gay people. The bio$-$engineer has not complained to you, but others have on his behalf. What would you do$?$
