I just came back from six weeks in America.
Personally prefer to take my holidays during the Australian winter, thus I can go somewhere warmer and escape the cold. Saying that I am going to Europe for Christmas, so I'll be swapping warm for cold! But I still plan to take some leave next year during the southern winter/northern Summer. I am thinking of going to Germany both times.
It is rather interesting to see how Vacations are views in America vs Australia.
Four weeks off, three weeks sick leave (both of which roll over if I want to hoarde my leave for a bigger holiday), a couple of company days, plus public holidays and I am also close to hitting long service (12 weeks extra landing in my account). Other then company days, this is the standard minimum by law across the board in Oz. My US friends couldn't believe that when I explained to them the minimum standard, as required by law.
My shortest amount of vacay in the last 8 years was last year, when I only took three weeks (but not all at once), because I was saving leave up for a bigger holiday this year.
I don't think I could move back to the States and be lucky to get two weeks only.
Everybody in my workplace, top to down, share there holiday stories and often help and give suggestions. Talking and planning holidays is the one thing that often unites the office!
In Australia, big holidays of 3-6 weeks if going overseas is very common (basically we're at the arse end of the world - it takes 24 hours to fly to Europe and at least 14 hours to the West Coast of America - so you might as well make it worth it). Saying that 2 weeks is more coming if going to South East Asia or New Zealand (as it is much sorter travelling times).
I envy Europe sometimes, you fly four hours and you've passed over 40 different countries and hundreds of different cultures and cities and experiences. I fly four hours... I am lucky to have made it to Darwin... :/
As for taking long vacations when I am one of two people that can do my job? I don't care. In Australia holidays are viewed as a way to recharge your batteries, if you don't take them, how can you remain motivated? If the company cannot backfill my roll when I am away, that is not my problem. I live my life for me, not my job. My company will start poking people to take annual leave around if you have at least six weeks in the kitty.
