I thought so.
Yeah, your travels made me think about the time off work I get, and the amount I'm paid... I've received yearly raises (or salary increases when switching jobs) since finishing school but no increase in vacation time. Last raise I got was enough to pay for a month of vacation and travel, so I'm planning on starting to take a month of unpaid leave every year to travel.
My last vacation time increase was a week (from 3 to 4), and as far as I know I'm only going to see that go up once I've worked at the place for.. maybe 2 more decades? Unless the union manages to negotiate a better deal for us at some point down the line, which would be amazing, but I'm not counting on it. The pay does go up on a regular basis, no complaints there.. but I wouldn't mind an increase in vacation time instead. And having said that we get like a week and a half off during Christmas time on top of that, so overall it's actually almost comparable to a bunch of European countries.
The best part about my work's vacation system is that it accumulates and never goes away. So I just wait until I have 4-5 weeks off, and take my vacation time in larger chunks. There's technically a rule that you can't have more than 25 days saved up, but it's not really enforced. Some managers eventually ask their employees to take Fridays off for a couple months until they're at a reasonable level.. and that happens more than you'd think - people suck at taking time off. Most people will take a day here, a day there, maybe go with the family somewhere for a couple days, and that's it... although I dare say I might have inspired coworkers to use up more of their vacation time in chunks. I think I've seen more and more people leave for a week or two in the last couple years.
My philosophy is that my trips are times of great potential for personal growth. I value this ability that I have to make these trips happen quite a bit - I'm not sure I could put a number on it, but you probably couldn't pay me more and reduce my vacation time to 2 weeks a year. $200k a year? I dunno, I wouldn't see the point. I make enough money now. $100k and 4 weeks vacation time? That would appeal to me a lot more I think. I'd rather spend 4 weeks in Madagascar than be able to buy a really nice flashy car or whatever.
An unpaid month off work to travel is a great idea, if that's something that's in your contract. Paid vacation time helps, but your idea to treat the increase in your income as "extra" money is a good one - with enough research & planning most of the world is probably at your fingertips.
My work just recently started this cool program where you go work at some other university somewhere else on the planet for a couple months. One girl from my office applied and.. I think she's going to Australia for 4 months? I forget where now.. but either way - a great opportunity - and something I might try to apply for at some point in the future too. It's also another example of how benefits can be more appealing to some people than pay increases - it depends on what your lifestyle is, where your interests lie, and what you value.
