The working environment in corporate America continues to improve for gay, lesbian, bisexual and transgender employees, in part due to increased competition for workers, a new study says.
Of the 446 corporations surveyed by the Human Rights Campaign, 138 achieved the highest possible score this year, up from 101 companies last year and doubling over the last four years.
The Corporate Equality Index analyzes the effects on gay, lesbian, bisexual and transgender employees of corporate practices, including whether companies have anti-discrimination policies, insurance benefits for partners, and diversity training.
Since last year, the number of companies prohibiting discrimination against transgender employees jumped 75 percent, the study says, and the number of employers offering at least one wellness benefit for transgender employees grew by 64 percent.
The number of corporations offering insurance benefits to same-sex partners was up 35 percent.
ExxonMobil, grocery chain Meijer and Perot Systems, all of which the study says offer no protections or benefits to gay, lesbian, bisexual and transgender employees, were the only surveyed companies to receive a score of zero on a scale of zero to 100.
