Ultimate Web Site Drop Down Menu Forum - Ask Slashdot: Does Being 'Loyal' Pay As a Developer?

An anonymous reader writes "As a senior developer for a small IT company based in the UK that is about to release their flagship project, I know that if I were to leave the company now, it would cause them some very big problems. I'm currently training the other two 'junior' developers, trying to bring them up to speed with our products. Unfortunately, they are still a long way from grasping the technologies used – not to mention the 'interesting' job the outsourced developers managed to make of the code. Usually, I would never have considered leaving at such a crucial time; I've been at the company for several years and consider many of my colleagues, including higher management, to be friends. However, I have been approached by another company that is much bigger, and they have offered me a pay rise of £7k to do the same job, plus their office is practically outside my front door (as opposed to my current 45 minute commute each way). This would make a massive difference to my life. That said, I can't help but feel that to leave now would be betraying my friends and colleagues. Some friends have told me that I'm just being 'soft' – however I think I'm being loyal. Any advice?"
