I didn't quit my job to take a vacation, but I took a long vacation once knowing that it would greatly increase my chances of getting laid off on the company wide layoffs that were coming up. I had already put in for a two week vacation, then I found out that the week before I was going to be on vacation, most of the company was going to be shut down for a week. But, my boss needed us in the warehouse to work during the shutdown, I said screw you, I'm taking a three week vacation now!!
I went to Arizona for a week to visit my sister and nephew. Then I came back home for one day, and left for New Zealand for two weeks to visit a friend. The company had layoffs three weeks after I got back from vacation, and I got axed! I loved it, I got three months severance pay!
