Apple CEO Tim Cook on Tuesday reiterated his call for Congress to approve the Employment Non-Discrimination Act (ENDA), which would prohibit workplace discrimination based on sexual orientation and gender identity.

Cook made his remarks in accepting a Lifetime Achievement Award from Auburn University, where he earned his bachelor's degree in industrial engineering.

Reading from an iPad, Cook said that respect for human dignity had led Apple to support ENDA.

“These values also guide us to educate the employees of companies we work with on their human rights. We've provided training for more than two million people around the world, many of whom work in our factories. These values lead us to insist that the companies we work with comply with our code of conduct, which in many cases goes far beyond laws.”

“These values have also recently guided us to support legislation that demands equality and non-discrimination for all employees, regardless of who they love. This legislation, known as the Employment Non-Discrimination Act, prohibits discrimination on the basis of sexual orientation or gender identity. I have long believed in this. And Apple has implemented protections for employees even when the laws did not. Now is the time to write these basic principles of human dignity into the book of law.”

“We have an opportunity to continue our progress with respect to race. And also to embrace immigration reform and eliminate discrimination of the GLBT community,” he added. (The video is embedded on this page. Visit our video library for more videos.)

Cook, who is rumored to be gay, first called for passage of ENDA in a Wall Street Journal op-ed last month.
