As if you didn't have enough to worry about with the weak economy and trying to hold onto your job: more employers than ever in the United States are offering their employees the benefit of flex hours, but their employees are refusing to take advantage for fear they'll get the axe! Recent research in the US by the Center for Work-Life Policy has found that fewer workers are accepting offers of flex-time—scheduling their own hours combined with working from home—because they feel the need to be present in the office to make sure their employers know they are working, even if the employees are in fact more productive working on their own schedules.
