This question already has an answer here:
This is a hypothetical scenario. One that I believe a lot of us have experienced.
Let's say I've been working at a company for X amount of time (not necessarily long-term). You receive a better offer from a company. Due to circumstances beyond your control (i.e. divorce, medical emergency, etc) your find yourself in a financial bind, you feel that it's in your best interest to quit your job and go for the higher paying one.
Do you mention this in your resignation letter? How do you discuss this with your boss or company? What's the best way to handle this? How will this act be perceived and how can I best mitigate any damage?
