You have just recently jumped from the CPA firm you spent four years at to a new position in the business. You've come on board at BigTech as a senior analyst in the financial planning and analysis department. You're pleased with the increase in your salary and by the promise of working fewer hours. Several months into your new job BigTech announces its annual drive for employee giving. You come to learn that the CEO of BigTech, a native and current resident of San Francisco, feels strongly about the issue of homelessness and favors a highly respected and well-established non-profit organization addressing that issue located in the city's Mission district. You further learn that, to your knowledge, and apparently without exception (at least as far as you can tell) every employee chooses to give 3 to 5 percent of their salary to this non-profit organization. 

In your own words, please offer your ethical reasoning (with well developed ethical arguments) for what is the right and ethical thing to do (is it right/ethical to participate in this program and to give to this charity or not) and WHY, using ONE school of thought (e.g., act utilitarianism, but not ethical egoism AND act utilitarianism) from EACH of the following major moral philosophies: 

teleology, 

deontology, and 

virtue ethics.
