The Human Rights Campaign Foundation has released the 2012 Corporate Equality Index.  The 100% ranking carries more weight than in previous years – and is more difficult to attain.

3 years ago the HRC provided participants notice that there would soon be more stringent qualifications for the 100% ranking.  How has it impacted employers?  Last year, 337 companies earned 100% rankings, and for 2012 the number dropped significantly to 190.

A few examples of the heightened requirements for companies to be ranked as best places to work for LGBT employees include:

• Increased emphasis on health benefits and full inclusion for transgender employees
• Demonstrating consistent organizational competency for LGBT employees
• Public commitment to the LGBT community

The 100% ranking is important for companies looking attract, hire, engage, and retain employees – in addition to gaining market share and support from the LGBT community and their allies.

Invitations to participate in the Corporate Equality Index Ranking are sent to all Fortune 1,000 companies from HRC.  Read the full report and rankings here.
