Is AUTHOR wrong in the post ? POST : So I have a predicament, I work in a small business (2 owners and in total 3 employees including me). I have been working here for about 8 years now.

And I recently found out that I can make more money and have double the time of I have now.
Easy decision,,except that they have trouble finding new employees and they need to have a certain amount of people by law. And both my other colleagues are leaving.

Would I be a asshole if I also quit and possibly ruin their chance to stay in business.

On a side note to make it more difficult, we work in the transport sector and my father own the company that they get their cargo from.
