Heather has worked at a paper mill company for the last 2 years as a front desk receptionist. Her co-worker, Maynard, has a very short temper while reading emails and blows up very quickly when he receives an email that critiques his work performance in any way. One day while both Heather and Maynard are working at the office, Maynard receives an email that criticizes him for not reaching his quota during the last quarter. Maynard promptly gets very angry and yells multiple racial and homophobic slurs at his coworkers, including Heather. She is so hurt by the language Maynard used that she resigns on the spot. Which court case in the readings would prevent Heather from suing her employer under a Title VII violation for Maynard’s actions?
