We have a modified version. We suggest 3 weeks of vacation spread throughout the year for all employees. They schedule on a shared calendar. We don’t keep track. Or add up at the end of the year. Just start over. We also allow personal days as needed and don’t keep track of sick days. And everyone gets a week between Christmas and New Years. But we are a tiny company. About 10 people. I am now going to poll everyone anonymously and see if this is ok for them. Never thought about it the way you presented it. That some might feel like being a competitive non-vacationer could reward their career aspirations, or worse feel that taking a vacation could be seen as a bad thing, is interesting to consider. Thanks!
