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.

Same here. I’d give my manager a month’s notice. And you’re so right about keeping it quiet.
