Google is highlighting its Gay pride efforts in a post to the official company blog today.

Google says about 300 of its employees marched in the 40th annual Pride parade in San Francisco, and more participated in various events in Boston, New York, Chicago, Tel Aviv, and Haifa. Googlers will also take part in EuroPride in Poland, parades in Tokyo and other cities, and will celebrate Pride season in Singapore.

Cynthia Yeung with Google’s Strategic Partner Development Team writes:

This year, we have another reason to celebrate. Google will be grossing-up imputed taxes on health insurance benefits for all same-sex domestic partners in the United States, retroactive to January 1, 2010. Starting July 1, we’ll also be providing the equivalent of the Family and Medical Leave Act for all same-sex domestic partners. And we’ve worked with our carriers to update their definition of infertility—it’s now defined as the inability to conceive a child with no stipulations on trying for one year.

Google supports its LGBT employees in many ways: raising its voice in matters of policy , taking a moment to remember the plight of transgender people around the world and going the extra mile to ensure that its employees are treated fairly.
