Hi,
Irrespective of the designated nature of duty, it will determine whether he/she falls within the purview of a workman or not. However, if he/she is engaged in managerial or supervisory activities such as having signing authority, directing juniors, performance evaluation and data analysis, planning to enhance the sales, etc., cannot fall within the definition of a workman under Section 2(S) of the ID Act, 1948.
With regard to your second query: it's not necessary to have basic salary equal to minimum wages. It can be split into certain allowances like HRA, Conveyance, LTA, Medical reimbursement, etc., provided that the gross salary should not be less than the minimum wages prescribed by the state government under Section 3 of the Minimum Wages Act. Also, the basic salary should not be less than 50% of gross to contribute to statutory benefits like EPF, Bonus, Gratuity.
The bonus threshold limit under Section 2(13) is basic plus DA, should not be more than 21,000.
Thanks & Regards,
