How about incentivised? Months back there was an HN post about a company that gives bonuses to people who take off... I think it was at least 25 days per year to ensure that people understand that taking time off is not a bad thing.
Meanwhile, in Europe, it's common to have between 4-7 weeks vacation per year, and it's seen as a bit weird not to use all of it. The social pressure around vacation goes in the completely opposite direction compared to the US.
