I've got a great job and great coworkers. While I wouldn't tell a soul I had won any money (being open about it will destroy your life), I would also make sure my departure from my job wouldn't leave people scrambling to pick up the pieces. Hell I'd probably stay longer than two weeks. That's not enough time to facilitate a smooth transition for my job.

Edit: That being said, there's no reason to respect a workplace that doesn't respect you back.

Very true, it sucks that so many jobs treat their employees like shit that most people can't fathom having enough respect for their work place to not fuck it over. Personally, I'm in the same boat as you. I'm treated well enough by my employer and co-workers. I would feel a moral obligation to make sure I don't leave them holding the bag even if I came into a ton of money and no longer needed the job.
