According to the passage, workers on flexitime………… .

In order to overcome the limits of the nine-to-five schedule and to grant workers increased independence, thousands of companies have been experimenting with flexible work hour schedules, or flexitime; with flexitime, workers set their own schedules as long as the hours are compatible with company needs and are sufficient to complete assignments. Thus one worker may work from seven to three while another works from ten to six. One variation of flexitime is the four-day work week, in which workers put in four ten-hour days rather than five eight-hour days. When possible, employees are allowed to choose their days off, with many choosing three-day weekends.
