Overworking is defined as indulging in work activities beyond your physical and mental capacity by increasing the workload and number of hours. It usually happens when the organizational structure is gamed to promote deadline-oriented work without providing adequate human resources.
Organizations ensure that the workers provide them with the required output at every cost, giving efficiency and project completion top-priority.
Many companies encourage overworking and employees feel that they are in a race to achieve more, and might get fired otherwise.
We forgot long ago that health is more important than money.
