State Rep. Mike Villarreal

If the Texas Legislature passes a bill to ban anti-LGBT employment discrimination in the upcoming session filed by state Rep. Mike Villarreal, D-San Antonio, the law would protect more than 400,000 workers, a new study finds.

The Williams Institute, a prominent LGBT think tank at UCLA, estimated that 431,095 LGBT workers live in Texas, according to U.S. Census data.

Research found adding sexual orientation and gender identity to the protected categories would have a minimal impact on state agencies and the budget, estimating that the changes would result in 203 more complaints a year. The number of additional complaints came from applying the national average of 4.7 complaints alleging discrimination in the workplace for every 10,000 LGBT workers to Texas’ number of LGBT workers.

The institute focused on research from 2008 that found 37 percent of gay and lesbian respondents to a survey had experienced workplace harassment and 12 percent were fired because of their sexual orientation. A 2010 survey of transgender people revealed that 78 percent experienced mistreatment at work.

“Data from other states show that the LGBT population files discrimination complaints at a rate similar to other protected groups, such as, women and people of color filing on the basis of sex or race,” co-author Christy Mallory, Reid Rasmussen Fellow of Law & Policy, said in a release. “However, the absolute number of complaints we expect to see from LGBT people is very low, because the LGBT population is small compared to other protected populations.”

The cost of reviewing and investigating the complaints by administrators would be low, costing $267,500–$334,400 in the first year and $248,600–$310,800 each subsequent year.

“We expect that enforcing these additional complaints will only cost the state approximately $300,000 in the first year; and the expenses will drop in the following years,” said co-author M.V. Lee Badgett, Williams Institute research director. “Although there is some administrative cost associated with enforcing these laws, they can also have positive effects on businesses and the state.”
