Well I was specifically talking about employee/employer relationships. An employer has a need for a skill that an employee can provide and pays said employee a salary under some contract. Nothing unusual there. If you're talking about "colleagues," then I assume everyone involved has significant first-class equity in the venture. This is a completely different work dynamic and requires much more care if one tries to leave the relationship. In such a case even more attention to the details of the contract is required. That being said you should reconsider working "all-nighters." Chronic sleep deprivation has some significant deleterious effects to your mental and physical health. As my intellect is my money-maker I do everything I can to preserve and enhance it. One of the easiest things I can do is get a good night's sleep. http://en.wikipedia.org/wiki/Sleep_deprivation http://en.wikipedia.org/wiki/Sleep_deprivation
