The search is underway to find the best Irish workplaces for gay, bisexual and transgender staff.

Companies employing a total of over 500,000 are involved in Ireland's first Workplace Equality Index.

It will also give a framework for employers to tackle issues like harassment and homophobic bullying.

It comes as almost 30% of gay and bisexual staff say they have been harassed at work.

While 10% say they have quit a job because of discrimination.

Director of workplace diversity at the Gay and Lesbian Equality Network (GLEN), Davin Roche, explains the idea behind the index.
