Walmart serves over 200 million customers per week across over 9,826 retail units in 28 countries. While Sam Walton envisioned saving people money to help them live better when founding the first Walmart over 40 years ago, the company has faced allegations of discrimination against women employees. Specifically, women have claimed they were shortchanged on pay and promotions, and that Walmart's health insurance and outsourcing practices negatively impacted employee loyalty. Several large lawsuits have been brought against Walmart alleging gender discrimination at its California stores. While Walmart maintains its purpose is to continue delivering savings to customers and members around the world with integrity, its treatment of female employees remains controversial.
