the fact that the workers do not only have rights they too also have responsibilities and obligations, that was the point under discussion.

Perhaps for you it was, Teribus. However, if you think that the way my daughter and I behaved was driven by contracts and workers'/employers rights and obligations, I have to disillusion you.   Certainly a contract exists, but that is the mere starting point and to stop there would be a thin gruel of a way of viewing the world, to my mind. Still, we each choose how we want to see things.
