Yep, that’s pretty much it.

Unlimited PTO is only good if you’ve proved yourself indispensable to the company, and can leverage that. Of course if you’re indispensable then it’s hard to take a lot of vacation!

Not OP, but probably yes. Unlimited PTO is not uncommon in tech.

Of course if you try to do some shenanigans like taking two months off they will simply fire you.

You hire more people.

I assume they run upgrades and backups?
