MILESTONE: Every Company On Fortune's Best 100 List Protects Gay Employees

Google is the nation's best company to work for according to the 2012 edition of Fortune Magazine's annual rankings. And for the first time, every company in the list's top 100 offers sexual orientation non-discrimination protections.

"It's been gathering strength over the 15 years that we've done the survey," said Milton Moskowitz, a co-author of the list. Similar progress has been made in benefits for same-sex domestic partners, which are now offered by 89 of the 100 companies listed, up from 70 five years ago. "It's not surprising to me that the places that are ranked the best to work are also the ones that are going to respect and value their employees," said Michael Cole-Schwartz, communications manager at the Human Rights Campaign, an organization that advocates on behalf of lesbian, gay, bisexual and transgender Americans.
