No blanket answer can be given to your question because a "Corporate Company" can be a composite organization; its administrative offices and direct sales emporia may come under the Shops and Establishments Act, while its manufacturing or processing units can be covered by the Factories Act, 1948. A person below the age of 18 years can be a child or a young person/adolescent. Regarding the definition of a child, there is no uniformity among the various legislations in force. For example, the Factories Act, 1948 defines a child as a person not having completed the age of 15 years, while the Child Labour (Prohibition and Regulation) Act, 1986 defines the same as a person not having completed the age of 14 years. [Due to my own doubt as to the present stage of the Amendment Bill 2012, I refrain from referring to it].
While the term adolescent is defined under section 2(b) of the Factories Act as a person who has completed 15 years of age but not 18 years, the term is not defined under the CLPR Act. However, the CLPR Act, 1986 prohibits the employment of a child in 18 occupations and 65 processes and regulates the conditions of working of children in other occupations/processes. So, my suggestion to you is to refer to the specific establishment-related Act applicable to the particular unit/branch of the Corporate Company and ascertain the restrictions, if any, about the employment of workers below 18 years, the maximum number of working hours per day, overtime work, etc.
