There are multiple companies that say they have policies that prohibit firing workers because they are gay, lesbian or transgender. One of those companies is Chicago energy giant Exelon, which was one of the businesses that joined the brief supporting LGBT workers. Exelon’s Vice President of Diversity and Inclusion Nicole Durham said the company prohibits discrimination of LGBT employees with anti-harassment training and policies. Durham added that if the court were to rule against LGBT workers, the company will still be committed to its gay and transgender employees.
