> Unlimited PTO is a scam

Well, no. It's just the target beneficiary is not you (the employees) but the employer.

Unlimited PTO resolves the employer from paying out PTO when they make you "redundant".

It's more than that. Unlimited PTO in practice also results in people taking less time off.

Some people have to be reminded to take time off for themselves (like me in my early years), and without a predefined amount of PTO and an expiration mechanism, there's nothing stopping them from going extended periods without taking any time for themselves.

Most people grow out of that eventually, but their gems turn black before they fully advocate for their own work/life balance.

The other side to that coin is that when employees take varying amounts of time off, it becomes easy for managers to pressure anyone taking more time off to conform with those who take less (and sometimes none at all).
