Americans' changing lifestyles over the past several decades has necessitated the institution of schedule flexibility at work, that is, shifts that are different from a business' normal hours. In surveying 556 full-time employed adults, Flex+Strategy Group/Work+Life Fit Inc. discovered that 97 percent said their supervisors allowed them some work-life flexibility last year. Yet, the occasional flex time isn't translating into many workers leading more balanced lives between home and work responsibilities. According to the survey, fewer than half of the respondents say that their employers are strongly committed to schedule flexibility. Even more troublesome to workers is that 45 percent say that their employers have either reduced flex time or may possibly do so in the future. Although flexible schedules are shown to improve work quality and morale, Flex+Strategy Group/Work+Life Fit Inc. says that some employers still aren't adept at managing workers with flex time, which causes them uncertainty about work-life programs.
