Under Chapter IV of the Code on Social Security, 2020, dealing with Employees' State Insurance, the provisions ordinarily apply to every establishment in which how many or more persons are employed?

Chapter IV of the Code on Social Security, 2020 (Sections 24 to 52), dealing with Employees' State Insurance, applies to every establishment in which ten or more persons are employed, or were employed, on any day of the preceding twelve months, subject to the wage ceiling notified by the Central Government. The Central Government retains discretionary power to extend ESI coverage to establishments carrying on hazardous or life-threatening occupations, irrespective of employee count, in the interest of worker safety. This threshold unifies the varying state-specific and sector-specific thresholds that existed under the erstwhile Employees' State Insurance Act, 1948.
