Why is Utilitarianism the best approach to business ethics?

John Stuart Mill's idea of rule utilitarianism is an ideal approach to business ethics due to consideration of not only the consumer but the employees. Rule utilitarianism is the belief that higher intellectual pleasures are more valuable than lower, physical pleasures. A higher pleasure may be a good relationship for example, whilst a lower pleasure would include something like eating food, being violent or some such other 'animalistic' desire or need. Mill argues that giving into lower pleasures is satisfying in the short term but intellectual pleasure would result in long term happiness. Therefore it would be the best approach to business ethics as it differentiates between lower pleasures, such as satisfying the consumer, and higher pleasures which may include treating the employees well and looking after their well-being at work.Furthermore, satisfying employees and regarding them as important would also imply that utilitarianism gives a kind of ethical moral conduct that would need to be upheld by the business.
In Jeremy Bentham's idea of utilitarianism, Act utilitarianism, it concerns what is in the best interest of a particular party, and so if an employee was mistreated, they may decide to quit. Unhappiness with employees would be detrimental for a business as they would lose employees and need to employ more people which adds to recruitment costs. Thus, by using the principles of utilitarianism it would bring into consideration the treatment of employees. Good treatment ensures employee satisfaction which in turn gains loyalty to the company or at least their jobs which is valuable to the business as they are valuable to the reputation and profit of the business. Overall doing this would bring about the most amount of overall happiness for both employer and employee and this therefore makes utilitarianism the best approach to business ethics.
