Which of the following legislations applies to workers in the unorganised sector in India?

All three laws reach workers in the unorganised sector. Section 5 of the Code on Wages, 2019 (which replaced the Minimum Wages Act, 1948) bars any employer from paying any employee less than the notified minimum rate of wages, and its coverage is not limited to scheduled employments or to the organised sector. Section 3 of the Child and Adolescent Labour (Prohibition and Regulation) Act, 1986 prohibits the employment of children in any occupation or process, wherever carried on. The Code on Social Security, 2020 defines "unorganised sector" and "unorganised worker" in section 2(85) and (86) and, in Chapter IX, requires the Central and State Governments to frame welfare schemes for unorganised workers.
