You said that employment is a fundamental right. That is essentially your question.
I believe rather that the fundamental right is the right to life and to income support. If income occurs through employment, that's wonderful, but life is sometimes fraught with difficulties. Unemployment does not only depend on an individual's will. When you lose your job, what do you do? Ideally, everyone should have a job, but the fact of the matter is that there are not jobs for everyone. There will always be a certain level of unemployment that cannot be eliminated.
