So at Mobile Jazz we made it a voluntary thing. After all you cannot force your employees to go anywhere ;-)
To Thailand only a few of us went, mostly for the family reasons.
However, to our most recent trip to the Austrian Alps we had almost everyone in the company head over there.
In general we're actually very pro-family. We do have a main office in Barcelona, but everyone is allowed to work from virtually anywhere. Some of us travel and work from remote locations, but for those with families it's also a great benefit to work from home and have more time with their families.
