If people aren't taking enough vacation, your company's culture is shit. They are afraid they will lose their jobs. Unlimited vacation is bullshit. A European might expect to take six weeks while your shitty company expects them to take two. Those differences cannot be resolved and eventually someone will get fired. It should be illegal to claim unlimited vacation unless one could literally be on vacation 100% of the time. Corporate assholes who coined this term and put such practices into existence should go fuck themselves. It's only there to look good on paper and save the company having to pay out vacation. Once again, American workers getting fucked over so their bosses can save a little money. In the long run, however, it's the business that gets fucked by burnt out, unmotivated employees. Deservedly so considering the scum who run most businesses. Those morons can't even see they are shooting themselves as well as everyone else in the foot. Such stupidity is the norm rather than the exception.
