Who's going to pay for it? Your employer. It's part of the cost of doing business. They're the people who are benefitting from your labour.
Workers who take vacations are more alert, more productive. They come back refreshed and energized.
It's always laughable to me that Republicans, who promote themselves as the party of family values, don't promote vacations, maternity and family leave. They oppose the ACA, early childhood education and more money for education - while sending their own kids to private schools.
Republicans oppose any measures to help families.
