Suppose an employer offers a base wage of $20 per hour for the first forty hours of work each week and overtime pay of $30 per hour for any hours beyond forty per week; the employer allows workers to choose their own hours of work. Suppose employee A chooses to work thirty-six hours per week and employee B chooses to work forty-two hours per week. Compute the average weekly earnings for employees A and B and the “earnings gap” (in percentage terms) between them. In your view, does this observed earnings gap constitute discrimination? Justify your conclusion.
