How to solve the following problem? You work with a team of 15 coworkers. Each of you works four hours a day, five days a week, during either the morning, afternoon, or evening shift. Your manager has left it up to the 15 of you to work out who will work which shift. No one really wants the evening shift. Right now, the six workers who are married are refusing to work the evening shift, arguing that they need time to be home with their spouses. They claim that their family needs are more important than the wishes of the unmarried workers, who would like evenings free to study or socialize. Your manager does not want to get involved in deciding who works which shift, but she wants to approve your final proposal.
