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.
The philosophy commonly called individualism is a philosophy of social cooperation and the progressive intensification of the social nexus. On the other hand the application of the basic ideas of collectivism cannot result in anything but social disintegration and the perpetuation of armed conflict.
