More than 250,000 Americans with disabilities are legally paid less than minimum wage for their work. Jordan Melograna wants that practice to end. He produced and directed the documentary “Bottom Dollars” to call attention to the issue, and the Brown and Providence communities have a chance to see it at the Student and Employee Accessibility Services’ annual Seaman Lecture. A panel discussion with Melograna and others follows a captioned and audio-described screening of the documentary. MacMillan Hall, Room 117, 167 Thayer Street.
