Liberals resolve this tension by reference to such general characteristics and goods as autonomy, rationality, and physical and mental health. Sometimes called primary goods, these are goods that are necessary in order to achieve what¬ever other goods an individual chooses to pursue. Consistent with the assump¬tions of the conventional model, work may simply be valued as a means for attaining whatever ends an individual chooses. However, if in the process of work these primary goods are destroyed or undermined, individuals have little chance of attaining their other ends. Thus, the liberal model argues that indi¬viduals have certain rights in the workplace and that these rights function to protect certain central and primary goods.
