Contrary to the downvotes, I agree with this sentiment. Technically you don't even need to give 2 weeks notice at most tech firms, it's completely at-will, so you can quit any time you like. Very few people do that though, and for good reason: unless there's a majorly important reason (i.e. death in family, horrible work incident, etc.), doing so leaves coworkers and management in the lurch.

Now, you might think, "I don't owe the company anything", and that's totally true. But at the end of the day, you are in fact working with other people, and how you treat other people (and how they perceive you are treating them) has consequences both on your interpersonal relationships with these people, and potentially on your future career path. Tech is a pretty small community, and people have a funny way of having way too many mutual connections, so quitting (and leaving colleagues in the lurch) might come back to bite you somewhere else down the line.

My advice is usually to quit with enough time to wrap things up or hand them off gracefully, and not to blindside anyone (unless, again, of extraordinary circumstances). This amount of time is totally position-dependent; for some it could be 3 days, for others (maybe the director of an organization) it could be months. But 2 weeks in all cases is nonsense - it's totally dependent on your situation and rapport with colleagues.

What makes you say that?
