Netflix (NFLX) is one of few large companies to offer unlimited vacation. "The philosophy is [that employers] don't need to track time anymore," says Leonard Sanicola of the nonprofit WorldatWork. "Everyone is professional." Vacation days aren't tallied for Netflix's salaried workers, but company policy makes it clear they can't slack off. "We don't measure people by how many evenings or weekends they are in the cube," the policy states. "We do try to measure people by how much, how quickly, and how well they get work done--especially under deadline." Netflix says it routinely cuts merely "adequate" employees.
