British businessman John Browne presents an argument for a workplace mindset of diversity and inclusion of LGBTQ+ people.

If you were being made to feel uncomfortable at work, how long would you stick around?

This concern is the core of The Glass Closet, John Browne's argument for the business benefits of embracing LGBTQ+ equality in the workplace.

John Browne had been BP's celebrated CEO since 1995, but in 2007 he resigned in disgrace.

Browne's homosexuality, which he had always kept private, had been exposed by the press amid a scandal over his attempts to silence a former partner.

Despite Browne's negative departure from BP, he ultimately realized that his life and work both improved once he came out.

As his career and name have rebounded, Browne is now an advocate for LGBTQ+ equality in business.

Published in 2014, The Glass Closet collects the thoughts, experiences, and learnings of more than 100 business professionals, executives, academics, psychologists, and diversity thought leaders on embracing LGBTQ+ identities in business.
