In reply to zarathustra:
Natives is good as is Snowheads for information on ski season opportunities.
A, genuinely, friendly word of advice though - when posting on either forum try and provide as much information as you can ie. what age are you (will dictate whether certain rolls are available), can you ski/board, what languages do you speak (German?), what skills do you have (handyman / chef, accountancy etc), what relevant work experience do you have (you say you're on a career break), where do you think you would like to work (chalet, ski shop, hotel, bar), do you have means to support yourself while you look for work out there or do you need something before you go with accommodation provide, do you have a preference on location ie. you want a jumping party town or you'd prefer something traditional.
All these things and many more will help people narrow down their comments so you get more relevant responses you can use rather than scatter-gun replies from other posters.
Good luck & enjoy it if and when you get there!
