(AP) — Two years after the city of Omaha adopted an ordinance aimed at protecting the workplace rights of gay and transgender employees, only a handful of complaints have been filed with the city’s Human Rights and Relationship Department.

City officials say they have not received many calls from business owners looking for help or clarification about the law, and they’re not aware of any lawsuits tied to the ordinance.

The Omaha City Council narrowly approved the ordinance in March 2012 that bans employers, job-training programs, labor groups and other organizations from discriminating based on a person’s sexual orientation. The measure included exemptions for religious organizations.
