Kohlberg's fifth level is the classical home of a moral philosophy called utilitarianism. The ethics of utilitarianism spans from Jeremy Bentham (1748–1832), John Stuart Mill (1806–1873), Henry Sidgwick (1838–1900), and G. E. Moore (1873–1958) to contemporary ethicist Peter Singer (2013). Utilitarianism is a philosophy which holds that an action, a law, or a rule is right only if it produces a good, preferable, or the best outcome. This is evident in utilitarianism's "Happiness Principle" stating that ethics must bring "the greatest good for the greatest number of people".⁵¹⁶ This creates a number of problems for HRM. First and foremost, HRM is not concerned with whether or not an action, a law, its own HR policies, or an organisational rule is right but with whether it delivers performance outcomes for the company.⁵¹⁷
