Most lesbian, gay, bisexual and transgender (LGBT) people remain closeted, or at least partially so, on the job because of a potentially hostile work environment. Many fear losing their job if they come out at work.

Employment protection based on sexual orientation and gender identity varies by state. But many companies have adopted their own protection policies because LGBT employees and straight allies organized to make it happen.

Companies large and small have employee groups to make sure LGBT workers are treated equal and fairly. Check out Lucent Technologies' Safe Space Program for ideas on how to start a similar program at your workplace.

The Human Rights Campaign (HRC) has further information on workplace diversity and LGBT employee resource groups.
