Apple has joined the growing chorus of companies backing passage of the LGBT-inclusive Houston Equal Rights Ordinance (HERO).

HERO prohibits discrimination in housing, employment and public accommodations based on several characteristics including race, religion, sexual orientation and gender identity.

Opponents of the law forced it onto Tuesday's ballot. Early voting ends today.

In a statement to Houston Unites, the campaign working to keep HERO, Apple reiterated its support for such non-discrimination measures.

“Apple is proud to be a part of Houston with four stores that employ over 500 people,” the company said. “Our stores and our company are open to everyone, regardless of where they come from, what they look like, how they worship or who they love. Apple supports Proposition 1 as it sends a clear message that Houston is focused on a future of inclusion, diversity and continued prosperity.”

Apple CEO Tim Cook has been a strong advocate for LGBT protections.
