While I'm hesitant to start an argument with you, the issue is not that simple. There are "natural right" strands of thought which would deny existence of a right to work, or similar ones ("2nd generation human rights"). But other schools of thought, possibly most, would affirm their existence.

The Universal Declaration of Human Rights (which the US voted for, while the USSR, Saudi Arabia and others abstained) does contain the rights to work, leisure, education, among others.

And the European Court of Human Rights, and other legal institutions, make these rights enforceable, too.

So, just saying "there is no such right" falls short.
