Debra Timmons, left, listens to information provided by Rachel Hefner of the nonprofit Virginia Organizing advocacy group about the campaign to secure paid sick leave for grocery store workers last Saturday outside the Food Lion in the 6800 block of Forest Hill Avenue. Ms. Hefner was among the group of activists who took part in a statewide campaign to educate shoppers about working conditions for supermarket employees. According to campaign information, only a few companies provide paid sick leave, leaving two-thirds of such workers uncovered.
