In some EU countries the laws mandate that it's the employers responsibility to provide the legally required vacation, because of the implict expectation that if the employee does not take the accrued vacation days then it's quite likely that it's not actually voluntary but because of some pressure by the employer or peers. Explicit pressure would be illegal, but since that's impractical to prove or enforce, 'sending' people to vacation (at least the minimum legal amount) is not just afforded, but required.
