EA, Microsoft and GameStop have scored the highest marks possible for its treatment of gay, lesbian, bisexual and transgender people, according to The Human Rights Campaign Foundation's Corporate Equality Index.
The index, which rates 583 US businesses on a scale from 0 to 100 per cent, awarded the three videogames companies full marks. Microsoft was noted as having achieved 100 per cent for its fourth consecutive while EA and GameStop have reached their second.
"The 2009 Corporate Equality Index shows that corporate America understands that a diverse workforce is critical to remaining successful and competitive," said the HRC Foundation president, Joe Solmonese.
"In the absence of a federal law that prohibits workplace discrimination based on sexual orientation and gender identity or expression, it is up to employers to take the lead and implement policies that ensure all their employees are protected."
