" Barger said polls show that 98 percent of the association's approximately 10,500 members favor a four-day work week. State agencies already have some flexibility to let employees telecommute or establish other "alternative work periods," said Office of Personnel Management executive director Oscar Jackson. "The four-day work week is relatively new," Jackson said, adding that he highlighted the proposal in a memo sent recently to agency directors. To make the four-day week work, agencies would have to determine whether they could close for one day each week or would have to develop a rotational assignment for employees that would allow the office to remain open five days a week. "There may, in fact, be some decisions over the next few weeks or months to determine whether or not a four-day work week for their particular agency would be appropriate," Jackson said. Among the chief concerns is how 10-hour work days would affect child-care options for parents. Copyright 2008 The Associated Press.
