One of these things is not like the others.
In Jasay's terminology, the first is a liberty (a relation between a person and an act) and the rest are rights {relations between two or more persons (at least one rightholder and one obligor) and an act}.

I was actually referring to the the third being what I might call an anti-liberty, i.e., you aren't allowed to work more than eight-hours a day, and the fact that is most definitely not enforced nor widely considered a human right.
