Entek International hired Shane Dawson, a male homosexual. Some of Dawson's co-workers, including his supervisor, made derogatory comments about his sexual orientation. Dawson's work deteriorated. He filed a complaint with Entek's human resources department. Two days later, he was fired. State law made it unlawful for an employer to discriminate against an individual based on sexual orientation. Could Dawson establish a claim for retaliation? Explain.
