IIRC they had PTO days which were apportioned pretty generously, but they didn't have sick days broken out separately. This doesn't mean they had less time off in general than the prevailing compensation packages. It was a great talking point for the media. However, TBH having a 'here's a bunch of time off, do what you need to with it' is kinda better than 'here's some time off for you to vacation, but then this other amount is only usable if you're sick, and if you're not sick it's money left on the table.'
