I think a large part of not saying "We need to work longer" is that if the work is interesting and rewarding enough, then employees will WANT to work longer. As soon as a manager says "We need to work longer", it generates an environment driven by employer demands instead of employee happiness. If you manage the work load at your company well enough, and the work environment is positive, then employees will be inclined to work longer out of desire to see the company excel.
