unlimited PTO is saying that "we would like to give you something that you can't potentially use". the sad reality is that in countries like France or Brazil where you have 30 days, it is actually guaranteed that you can take that many days off, while unlimited PTO startup employees end up using 10-15 days per year of the "unlimited PTO". it is like a bait to get more people to work for them without actually giving anything. I would argue that we need 4 days work weeks that would be fair. The reason why we have 5 days is purely based on the greed of the corporations. if i open my startup I am going to offer 4 days workweeks instead of unlimited PTO, that is a better way to respect your employees that giving a useless bait.
