Out of respect for family life, PortionPac never runs three shifts; it changed work schedules so employees can spend more time with their kids. Salespeople receive bonuses for not selling clients too much product. The factory floor is cool and lit by natural light. Machines were designed to run quietly so workers can chat. Once a year, executives and managers spend a day laboring in the plant, looking for ways to make the work easier.
