In France they are civil unioning

I did some Googling and found this link.

It's a list of federal laws regarding discrimination in employment.
The second section is a listing of Discriminatory Practices
This link has only a rather oblique mention of sexual orientation:

The Office of Personnel Management (OPM) has interpreted the prohibition of discrimination
based on conduct to include discrimination based on sexual orientation.

<snip>
Note: Many states and municipalities also have enacted protections against discrimination
and harassment based on sexual orientation, status as a parent, marital status and political affiliation.
For information, please contact the EEOC District Office nearest you.

"Conduct" sounds as though it applies only to current employees, not necessarily to prospective employees.

I'm interested in this because my assumption now is that with DADT repealed for the US military,
prohibiting discrimination based on sexual orientation will follow into the civilian population,
in the same way the military effectively lead the way on ending discrimination based on race.
