such as not renewing its membership in the National Gay and Lesbian Chamber of Commerce. In January 2006, Walmart announced that "diversity efforts include new groups of minority, female and gay employees that meet at Walmart headquarters in Bentonville to advise the company on marketing and internal promotion. There are seven Business Resource Groups: women, African-Americans, Hispanics, Asians, Native Americans, Gays and Lesbians, and a disabled group." Poorly run and understaffed stores In 2015, the Walmart CEO acknowledged a need for Walmart to refocus on cleanliness and tidiness, restocking shelves quickly, integration with digital, sideline businesses such as gas stations and care clinics, better selection such as in fresh produce, and correcting the situation in which Walmart prices were not always as low as those of competitors.
