Detailed Description

India is the seventh-largest country by geographical area and the second-most populated country in the world. Almost ninety-four percent of the Indian workforce is working in the unorganised sector. Unorganized activities are labor-intensive, necessitating low-level skills and relying on age-old, primitive technologies that pose occupational hazards. Occupational stress can be divided into four major classes, such as physiological stress, postural stress, psychological stress, and environmental stress. The earlier research on the unorganised sector recommends ergonomic design interventions to improve workstation ergonomics. more ergonomic. Mechanization or automation in India, like in other developed countries, is prevalent. An unorganised sector is difficult. Therefore, it needs a context-specific, low-cost design. intervention from the viewpoints of sustainability, cost-effectiveness, and manpower employment, which can reduce occupational stress. It is essential to find out the most significant In the unorganised sector, there is a pain point for doing context-specific design interventions. Hence, the prioritisation of the most painful stress among all other occupational stresses is most important. A physiologically stressful job demands a high physical workload and needs to be redesigned to provide leverage or low-cost mechanization. The pastorally stressful job must be eliminated. change the working posture. The causes of psychologically stressful jobs must be discovered. psychological stress, reorganise the job, and improve the employer-employee relationship. For an environmentally stressful job, the working environment needs to be modified by the worker. acceptable limit. An environmental stressor can be managed at the source or in between the source and the subject (like using PPE).

The Minimum Wage Act, 1948, helps with the fixation and execution of minimum wages to prevent exploitation of labour through the payment of low wages. The minimum wage rate can be fixed at a) a time rate, b) a piece rate, c) a guaranteed time rate, and d) an overtime rate. The Indian Labour Conference (1957) had come up with a norm that should be considered during minimum wage fixation. Minimum wages in India's unorganised sector are set at 2700 calories per day. Ergonomics can validate unorganised workers' energy requirements. The minimum wage fixation committee considers four consumption units per earner. But in the Indian scenario, there are six consumption units per earner (worker, spouse, two kids, and parents). Social scientists must reconsider wage fixation norms in light of this.
