Another example of utilitarianism in the workplace would be an amoral stance on one's career, in this case. In order for them to get promoted they must sacrifice the time they spend with their family. Sure being mean to your family is morally wrong, but some people really thinks that depriving their family of their time is most useful in terms of furthering their career. I remember one of my family members worked at car factory when I was little; (actually he still works there today). He is always working a lot of long hour’s everyday instead of being at home with his wife and kids.

How does one make a utilitarian-based decision in a case like this?

You are forgetting, many folks use the workplace to satifify family and social needs. It is a family just like the one at home. Additionally, one can get paid for being with that family. Which one does the person get the most benefit from. I am thinking of the relationship to polygamy, also.

To make a utilitarian-based decision in a case like this, you would need to assess the overall consequences of each course of action from a utilitarian perspective. Utilitarianism is a consequentialist ethical framework that focuses on maximizing overall happiness or well-being.

Here's a step-by-step process to make a utilitarian-based decision in the given scenario:

1. Identify the available options: In this case, the person has two options to consider - spending more time with the family or dedicating more time to work for career advancement.

2. Consider the happiness and well-being of all affected parties: Utilitarianism requires considering the greatest happiness for the greatest number of people. Assess the potential positive and negative consequences for each option on both the individual and the family.

- Spending more time with the family: This would likely lead to increased happiness and well-being for the family members, fostering stronger relationships and emotional support. It may also promote a healthier work-life balance and contribute positively to the individual's own well-being.

- Sacrificing time for career advancement: This could lead to potential positive consequences such as financial stability, professional growth, and increased opportunities for the individual in the long run. However, it may have negative consequences on family relationships, emotional well-being, and quality of life for both the individual and their family.

3. Weigh the potential consequences: Evaluate and compare the short-term and long-term impacts of each option. Consider factors such as happiness, well-being, financial stability, personal growth, and family dynamics.

4. Determine which option maximizes overall happiness or well-being: Look for the option that provides the greatest net positive impact on overall happiness or well-being. Consider both the short-term and long-term effects, as well as the well-being of all affected parties.

Remember, utilitarianism focuses on the greater good and maximizing overall happiness. The decision would ultimately depend on the individual's values, priorities, and personal circumstances. Utilitarianism does not provide a definitive answer, but it offers a framework to consider the consequences and make an informed decision.
