Overtime is voluntary and employees have the right to refuse. There is at least one case (SEAWUSA v Trident Steel (1986) 7 ILJ 86 (IC)) where the court held that an employer can dismiss employees who persistently and unreasonably refuse to work overtime. That is even if there is no contractual obligation to do so.
Individualistic cultures are oriented around the self, independent instead of identifying with a group mentality. They see each other as only loosely linked, and value personal goals above that of the group.
America's individualism, however, means that there is a wide variety of opinions on almost every political issue and every public policy problem. There are, however, identifiable core beliefs that help define American political culture. These beliefs include, as noted, a strong emphasis on individual liberty, support for equality (especially political equality), a belief in majority rule and faith in the Constitution and the form of government it establishes.
