Basically take however many weeks of vacation and consider it a month. So, as a new hire, you get two weeks vaca. But each one can easily be manipulated into a month. At 3 weeks like I have now, I have 3 months vaca per year. I space it so I have every 4th month off. In 5 years I'll do that every 3rd month. So, in 5 years I'll work a maximum of 2 months at a time, then have a month off. That's what I do, some take an entire summer off with their kids. It's great.
