Those cons just make it shady. If you give me unlimited then I'm taking at least 2 weeks probably at one time and another week or 2 on there own at Christmas and some other time and potentially a day every month. Because it's all about balance and companies in the US don't think we need life balance in the work/life balance. I'd love to work at one of the places that gives you like a month/unlimited and money for the vacation, a place that basically forces you into it

not that I'd spend it on the beach but in museums and cities and disney parks around the world.
I will say when I worked at the race team we had vacation but not sick days. We could and did call in sick or go to dr appts etc without any vacation being taken away. I even managed to squeeze out a personal day a couple of times for mental health, my boss also liked me

What I noticed was for the most part people would stay home when they were sick and they weren't coming in if they were sick enough to be at home. Allergies or a cold they'd be in but you would be at any job. I'm not sure if it worked because you didn't feel like you only had x days for being sick or what it was but the last place I worked where it was straight PTO regardless of reason so many more people came in sick because they wanted to use it for vacation. So at the very least I don't agree with lumping it all together. This last job also didn't pay us for any unused vacation and we couldn't roll it over, so that's not an everywhere thing.
