Efforts to bring a four-day workweek pilot program to Maryland is over at least for this year. Sponsors of the House and Senate bills withdrew the legislation amid concerns it would institutionalize a 32-hour work week. Costs of the five-year pilot program and engrained attitudes concerning the traditional 40-hour work week appear to have derailed legislation for this year. Del. Vaughn Stewart, (D-Montgomery), held out hope of a study by the state Department of Labor, which lawmakers could still require this session through a budget amendment.
