The correct option is Absence of job security and social benefits
Explanation
In the structure of the Indian workforce, casual wag are defined as workers casually engaged in others' farm or non-farm enterprises, receiving wages based on daily or periodic contracts. They constitute a major part of the unorganized (informal) sector.Analysis of Options:
- Absence of job security and social benefits is Correct: The defining characteristic that creates extreme vulnerability for casual wage labourers is the absence of job security and social benefits. Unlike regular salaried employees, they lack written contracts, protection against arbitrary dismissal, and social security nets such as the Provident Fund (PF), pension, or health insurance.
- Restriction to rural areas is Incorrect: Casual wage labour is not restricted to rural areas. It is prevalent in both rural areas (e.g., agricultural labourers) and urban areas (e.g., construction workers, coolies, and daily wage earners).
- Prohibition of trade unions is Incorrect: There is no legal prohibition of trade unions for casual labourers. While forming unions is practically difficult due to the scattered and temporary nature of their employment, it is not forbidden by law.
- High tax liability is Incorrect: Casual wage labourers typically belong to the lowest income strata. Consequently, they generally fall below the taxable income threshold and do not face high tax liability.
Key Takeaway:
The primary distinction between regular salaried employment and casual wage labour is the provision of social security benefits and employment stability. The lack of these protections makes casual labourers the most vulnerable workforce segment.
