This sounds like a different side of the planet. (checks user details) Yes, it is. :D

Here the cultural preference is one employment for life for average jobs, and for IT jobs I would guess 5 or 10 years per job. (For more adventurous people, there is an opportunity to do 3-12 months contracts for foreign companies, but this includes either a lot of travelling or living abroad. This is mostly done as a sole proprietorship, which means that if you happen to screw up something, say goodbye to your property. I have considered that too, but unfortunately I hate travelling.)
