Hugh Pickens writes "Chad Brooks reports that a steady stream of research over the past year reveals that Americans aren't taking vacations and it's because they are afraid to take time off from work for fear of appearing less than dedicated to their employer with one survey showing that 70 percent of employees said they weren't using all their earned vacation days in 2011. 'You have this kind of fear of not wanting to be seen as a slacker,' says John de Graaf, executive director of Take Back Your Time, an organization focused on challenging the epidemic of overwork, over-scheduling and time famine facing society. De Graaf adds that while some companies are good about encouraging employees to use earned time off, there also are some that aren't worried about the potential repercussions that may come from that nose-to-the-grindstone approach. 'They think, "If I burn someone out, I can always find someone else,"' says de Graaf. 'They think [employees] are expendable.' Even when they do take vacation, research shows many employees aren't leaving their work behind. In one study, 66 percent of surveyed employees said they would check and respond to email during their time off, and 29 percent expect to attend meetings virtually while on vacation. De Graaf is not optimistic anything will ever get done to free employees of their fear of taking time off. 'This is the only wealthy country in the world that does not guarantee any paid vacation time,' says de Graaf. 'Every other country understands that this makes people healthier and creates a better workforce.'"
