BACKGROUND AND OPPORTUNITY

There are almost 75 million hourly workers in the United States, representing more than half of the entire workforce. Historically, managing hourly employees has been difficult due to high attrition (average of 60%) and high replacement costs (average of $3,200 per employee in retail). The ongoing labor shortage and competition from the gig-economy, make it more difficult to attract and retain hourly employees.The top reasons hourly employees leave their jobs are a lack of schedule empowerment, poor communication with employers, and an inability to get paid early. Gen Z and the millennial workforce demand gig-like flexibility, modern technology, and compelling work options.Legion’s mission is to turn hourly jobs into good jobs, serving the hourly workers who make up the majority of the US workforce.
